-Contributing to GNU Stow
-========================
-
-Development of Stow, and GNU in general, is a volunteer effort, and
-you can contribute.  If you'd like to get involved, it's a good idea to join
-the [stow-devel](https://lists.gnu.org/mailman/listinfo/stow-devel)
-mailing list.
-
-Bug reporting
--------------
-
-Please follow the procedure described in [the "Reporting Bugs"
-section](https://www.gnu.org/software/stow/manual/html_node/Reporting-Bugs.html#Reporting-Bugs)
-of [the manual](README.md#documentation).
-
-Development
------------
-
-For [development sources](https://savannah.gnu.org/git/?group=stow)
-and other information, please see the [Stow project
-page](http://savannah.gnu.org/projects/stow/) at
-[savannah.gnu.org](http://savannah.gnu.org).
-
-There is also a
-[stow-devel](https://lists.gnu.org/mailman/listinfo/stow-devel)
-mailing list (see [Mailing lists](README.md#mailing-lists)).
-
-Please be aware that all program source files (excluding the test
-suite) end in `.in`, and are pre-processed by `Makefile` into
-corresponding files with that prefix stripped before execution.  So if
-you want to test any modifications to the source, make sure that you
-change the `.in` files and then run `make` to regenerate the
-pre-processed versions before doing any testing.  To avoid forgetting
-(which can potentially waste a lot of time debugging the wrong code),
-you can automatically run `make` in an infinite loop every second via:
-
-    make watch
-
-(You could even use fancier approaches like
-[`inotifywait(1)`](https://www.man7.org/linux/man-pages/man1/inotifywait.1.html)
-or [Guard](https://guardgem.org/).  But those are probably overkill in
-this case where the simple `while` loop is plenty good enough.)
-
-Testing
-~~~~~~~
-
-The test suite can be found in the [`t/`](t/) subdirectory.  You can
-run the test suite via:
-
-    make check
-
-Tests can be run individually as follows.  First you have to ensure
-that the `t/`, `bin/`, and `lib/` directories are on Perl's search path.
-Assuming that you run all tests from the root of the repository tree,
-this will do the job:
-
-    export PERL5LIB=t:bin:lib
-
-(Not all tests require all of these, but it's safer to include all of
-them.)
-
-Secondly, be aware that if you want to test modifications to the
-source files, you will need to run `make watch`, or `make` before each
-test run as explained above.
-
-Now running an individual test is as simple as:
-
-    perl t/chkstow.t
-
-or with a given debugging verbosity corresponding to the `-v` / `--verbose`
-command-line option:
-
-    TEST_VERBOSE=4 perl t/chkstow.t
-
-The [`prove(1)` test runner](https://perldoc.perl.org/prove) is another
-good alternative which provides several handy extra features.  Invocation
-is very similar, e.g.:
-
-    prove t/stow.t
-
-or to run the whole suite:
-
-    prove
-
-However currently there is an issue where this interferes with
-`TEST_VERBOSE`.
-
-If you want to create test files for experimentation, it is
-recommended to put them in a subdirectory called `playground/` since
-this will be automatically ignored by git and the build process,
-avoiding any undesirable complications.
-
-Test coverage
-~~~~~~~~~~~~~
-
-To view test coverage reports, first ensure that
-[`Devel::Cover`](https://metacpan.org/dist/Devel-Cover) is installed.
-Then type `make coverage`.  The last lines of the output should
-include something like:
-
-    HTML output written to /home/user/path/to/stow/cover_db/coverage.html
-
-which you can open in a web browser to view the report.
-
-Translating Stow

-Stow is not currently multi-lingual, but patches would be very
-gratefully accepted. Please e-mail
-[stow-devel](https://lists.gnu.org/mailman/listinfo/stow-devel) if you
-intend to work on this.

-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
 this License.
 
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
+  7. If, as a consequence of a court judgment or allegation of patent
-patent license under the contributor's essential patent claims, to
+infringement or for any other reason (not limited to patent issues),
-make, use, sell, offer for sale, import and otherwise run, modify and
+conditions are imposed on you (whether by court order, agreement or
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work

+Basic Installation
+==================
+
+Stow is a Perl script.  You must have Perl 5.005 or later in order for 
+it to run.
+
+The steps in building stow are:
+
+1.  `cd' to the directory containing the source code (and this file)
+    and type `./configure' to configure stow for your system.  This
+    step will attempt to locate your copy of perl and set its location
+    `Makefile.in'.
+
+2.  Type `make' to create `stow' and `'stow.info'. If perl could not
+    be found by `./configure', you'll have to edit line 1 of `stow' 
+    from `#!false' to `#!/path/to/perl' (where /path/to/perl is wherever
+    perl will be found when stow runs).
+
+3.  Type `make install' to install `stow' and `stow.info'.
+
+4.  You can remove the generated files from the source code directory
+    by typing `make clean'.  To also remove the files that `configure'
+    created (so you can compile the package for a different computer),
+    type `make distclean'.  There is also a `make maintainer-clean'
+    target, but that is intended mainly for stow's developers.  If you
+    use it, you may have to get all sorts of other programs in order
+    to regenerate files that came with the distribution.
+
+Installation Names
+==================
+
+By default, `make install' will install the package's files in
+`/usr/local/bin' and `/usr/local/info'.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure'
+the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Since `stow' is concerned with separating a package's installation
+tree from its run-time tree, you might want to install `stow' into a
+directory such as `/usr/local/stow/stow' but have it run out of
+`/usr/local'.  Do this by giving the run-time prefix (e.g.,
+/usr/local) to configure as described above; then run `make'; then run
+`make install prefix=/usr/local/stow/stow'.  For more information on
+this technique, see the Stow manual.
+
+The configuration system
+========================
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' and to create the `stow' script
+itself, using Makefile.in and stow.in as templates.  Finally, it
+creates a shell script `config.status' that you can run in the future
+to recreate the current configuration, a file `config.cache' that
+saves the results of its tests to speed up reconfiguring, and a file
+`config.log' containing other output.
+
+The file `configure.ac' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.ac' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The file `Makefile.am' is used to create `Makefile.in' by a program
+called `automake'.  You only need `Makefile.am' if you want to change
+it or regenerate `Makefile.in' using a newer version of `automake'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

-How to install GNU Stow
-=======================
-
-Prerequisites
--------------
-
-Stow is a collection of Perl scripts and modules.  You must have Perl
-5.6.1 or later in order for it to run.  The test suite also requires
-the `Test::More` and `Test::Output` modules which can be obtained from
-CPAN.  They are also available as packages in some of the GNU/Linux
-distributions.
-
-Installation methods
---------------------
-
-Stow can either be installed via the standard GNU Autotools procedure
-(`./configure && make install`) or since 2.1.0, via CPAN-style via
-Module::Build.
-
-Advantages of the Autotools approach:
-
-  - It's arguably more flexible.
-
-  - It will install the documentation in Info, HTML, man, and PDF
-    formats.
-
-Advantages of the `Module::Build` approach:
-
-  - It's more in keeping with the standard way to distribute CPAN
-    modules.
-
-  - It performs dependency checking to ensure you have the necessary
-    Perl modules installed.
-
-Both approaches are described in detail below.  However if you are
-building from the git repository rather than an official release,
-you first need to perform some extra steps:
-
-Preparatory steps required only when building from git
-------------------------------------------------------
-
-`configure` and `Makefile` are included in official releases of Stow,
-but they are deliberately omitted from the git repository because they
-are autogenerated.  Therefore if you are installing directly from git,
-you first need to generate them as follows.
-
-First `cd` to the directory containing the source code (and this
-file), and then run:
-
-    autoreconf -iv
-
-If this runs successfully then you are ready to continue with one of
-the two installation methods below.
-
-Basic Installation via `Module::Build`
---------------------------------------
-
-The steps in building Stow are:
-
-1.  `cd` to the directory containing the source code (and this file).
-
-2.  If you are building from an official GNU release tarball, type
-    `./configure && make` to configure stow for your system.  If you
-    are building from a CPAN tarball, this step can be skipped.
-
-    If `make` warns that the Perl module installation directory is
-    not in `@INC`, then you should run:
-
-        eval `perl -V:siteprefix`
-        ./configure --prefix=$siteprefix && make
-
-    to avoid a superfluous `use lib` line in your stow executable.
-
-3.  Type `perl Build.PL`.
-
-4.  Type `./Build install` to install the various files.  As noted
-    above, this installs fewer files than the Autotools installation.
-
-Basic Installation via Autotools
---------------------------------
-
-The steps in building Stow are:
-
-1.  `cd` to the directory containing the source code (and this file).
-
-2.  Type `./configure` to configure stow for your system.  This step
-    will attempt to locate your copy of perl and set its location in
-    `Makefile.in`.  You can use the normal arguments to change the
-    default installation paths (see below); additionally you can use
-    the
-
-        --with-pmdir=/path/to/perl/modules
-
-    option to manually choose where the Perl modules get installed.
-    However, if you don't, the `configure` script will go to great
-    lengths to try to choose a sensible default.
-
-3.  Type `make install` to install the various files.  If the chosen
-    installation directory for Perl modules is not included in Perl's
-    built-in `@INC` search path, the Makefile rules will automatically
-    insert a
-
-        use lib "...";
-
-    line into the generated stow script to ensure that it can always
-    locate the Perl modules without needing to manually set `PERL5LIB`.
-
-4.  You can remove the generated files from the source code directory
-    by typing `make clean`.  To also remove the files that `configure`
-    created (so you can compile the package for a different computer),
-    type `make distclean`.  There is also a `make maintainer-clean`
-    target, but that is intended mainly for stow's developers.  If you
-    use it, you may have to get all sorts of other programs in order
-    to regenerate files that came with the distribution.
-
-Installation Names
-------------------
-
-By default, `make install` will install the package's files in
-`/usr/local/bin` and `/usr/local/info`.  You can specify an
-installation prefix other than `/usr/local` by giving `configure` the
-option `--prefix=PATH`.
-
-If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure`
-the option `--program-prefix=PREFIX` or `--program-suffix=SUFFIX`.
-
-Since `stow` is concerned with separating a package's installation
-tree from its run-time tree, you might want to install `stow` into a
-directory such as `/usr/local/stow/stow` but have it run out of
-`/usr/local`.  Do this by giving the run-time prefix (e.g.,
-/usr/local) to configure as described above; then run `make`; then run
-`make install prefix=/usr/local/stow/stow`.  For more information on
-this technique, see the Stow manual.
-
-The configuration system
-------------------------
-
-The `configure` shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile` and to create the `stow` script
-itself, using Makefile.in and stow.in as templates.  Finally, it
-creates a shell script `config.status` that you can run in the future
-to recreate the current configuration, a file `config.cache` that
-saves the results of its tests to speed up reconfiguring, and a file
-`config.log` containing other output.
-
-The file `configure.ac` is used to create `configure` by a program
-called `autoconf`.  You only need `configure.ac` if you want to change
-it or regenerate `configure` using a newer version of `autoconf`.
-
-The file `Makefile.am` is used to create `Makefile.in` by a program
-called `automake`.  You only need `Makefile.am` if you want to change
-it or regenerate `Makefile.in` using a newer version of `automake`.
-
-Sharing Defaults
-----------------
-
-If you want to set default values for `configure` scripts to share,
-you can create a site shell script called `config.site` that gives
-default values for variables like `CC`, `cache_file`, and `prefix`.
-`configure` looks for `PREFIX/share/config.site` if it exists, then
-`PREFIX/etc/config.site` if it exists.  Or, you can set the
-`CONFIG_SITE` environment variable to the location of the site script.
-A warning: not all `configure` scripts look for a site script.
-
-Operation Controls
-------------------
-
-`configure` recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE`
-     Use and save the results of the tests in FILE instead of
-     `./config.cache`.  Set FILE to `/dev/null` to disable caching, for
-     debugging `configure`.
-
-`--help`
-     Print a summary of the options to `configure`, and exit.
-
-`--quiet`
-`--silent`
-`-q`
-     Do not print messages saying which checks are being made.
-
-`--srcdir=DIR`
-     Look for the package's source code in directory DIR.  Usually
-     `configure` can determine that directory automatically.
-
-`--version`
-     Print the version of Autoconf used to generate the `configure`
-     script, and exit.
-
-`configure` also accepts some other, not widely useful, options.

 News file for Stow.
 
-* Changes in version 2.4.0
+*  Changes in version 2.0.1:
-
+** Defer operations until all potential conflicts have been assessed.
-*** --dotfiles now works with directories
-
-    A long-standing bug preventing the --dotfiles option from working
-    correctly with directories has been fixed.
-
-    It should also works in combination with the --compat option.
-
-*** Eliminated a spurious warning on unstowing
-
-    2.3.1 introduced a benign but annoying warning when unstowing
-    in certain circumstances.  It looked like:
-
-      BUG in find_stowed_path? Absolute/relative mismatch between Stow dir X and path Y
-
-    This was caused by erroneous logic, and has now been fixed.
-
-*** Unstowing logic has been improved in other cases
-
-    Several other improvements have been made internally to the
-    unstowing logic.  These changes should all be either invisible
-    (except for changes to debug output) or improvements, but if you
-    encounter any unexpected behaviour, please report it as directed
-    in the manual.
-
-*** Improved debug output
-
-    Extra output resulting from use of the -v / --verbose flag
-    now appears in a more logical and understandable way.
-
-*** Janitorial tasks
-
-    Users are not substantially affected by these changes.
-
-***** Added some more information from the web page to the README
-
-***** Made some improvements to the documentation
-
-***** Improve readability of source code
-
-      Quite a few extra details have been added in comments to clarify
-      how the code works.  Many variable names have also been
-      improved.  The comments of many Stow class methods have been
-      converted into Perl POD format.
-
-***** Added a =CONTRIBUTING.md= file
-
-***** Add a =watch= target to =Makefile=
-
-      =make watch= provides easy continual pre-processing during
-      development, which reduces the risk of debugging the wrong code.
-
-***** Removed texinfo.tex from the distribution
-
-      This eliminates existing and future bit-rot.
-
-***** Updated aclocal.m4 from 1.15.1 to 1.16.5
-
-      This mostly just updates copyright notices to 2021, and URLs to https.
-
-***** Replace broken gmane links with links to lists.gnu.org
-
-      [[https://lars.ingebrigtsen.no/2020/01/06/whatever-happened-to-news-gmane-org/][gmane has been dead for quite a while.]]
-
-***** Improve support for navigating / editing source via emacs
-
-******* Support source navigation in emacs via [[https://github.com/jacktasia/dumb-jump][dumb-jump]].
-
-******* Configure cperl-mode to match existing coding style.
-
-*** Various maintainer tweaks
-
-    Further improved the release process and its documentation in
-    various minor ways.
-
-* Changes in version 2.3.1
-
-*** Remove dependencies on Hash::Merge and Clone::Choose
-
-    stow 2.3.0 added external runtime dependencies on Hash::Merge and
-    Clone::Choose. Historically stow hasn't had runtime dependencies
-    other than Perl itself, which is a useful property if you're
-    managing the installation of Perl using stow; the bootstrapping
-    instructions in stow's manual would need updating to describe how
-    to install these two modules (and any dependencies they have now
-    or in the future) as well.
-
-    However, Hash::Merge is much more general than stow actually
-    needs, so replace the merge() call with a few lines of equivalent
-    code -- this avoids the external dependencies, and is clearer than
-    the merge() call.
-
-    Many thanks to Adam Sampson for this patch!
-
-    https://lists.gnu.org/archive/html/bug-stow/2019-06/msg00001.html
-
-*** Fix an issue with the test suite
-
-    t/cli.t was not testing with the right Perl executable, as
-    reported here:
-
-        https://rt.cpan.org/Ticket/Display.html?id=129944
-
-    Thanks to Slaven Rezic for spotting this and reporting it!
-
-*** Various maintainer tweaks
-
-    Improved the release process and its documentation in various
-    minor ways.
-
-* Changes in version 2.3.0
-
-*** New features / changes in behaviour
-
-***** New --dotfiles option
-
-      Enable special handling for "dotfiles" (files or folders whose name
-      begins with a period) in the package directory. If this option is
-      enabled, Stow will add a preprocessing step for each file or folder
-      whose name begins with "dot-", and replace the "dot-" prefix in the
-      name by a period (".").  This is useful when Stow is used to manage
-      collections of dotfiles, to avoid having a package directory full
-      of hidden files.
-
-      For example, suppose we have a package containing two files,
-      stow/dot-bashrc and stow/dot-emacs.d/init.el.  With this option,
-      Stow will create symlinks from .bashrc to stow/dot-bashrc and from
-      .emacs.d/init.el to stow/dot-emacs.d/init.el.  Any other files,
-      whose name does not begin with "dot-", will be processed as usual.
-
-      Thanks to Joris Vankerschaver for this feature!
-
-***** Shell-like expansion in .stowrc files
-
-      For options within .stowrc files which describe file paths, "~" can
-      be included to expand to the current value of $HOME, and
-      environment variables can be referenced e.g. via "$FOO" or
-      "${FOO}".  To prevent expansion, escape with a backslash.
-
-      Thanks a lot to Charles LeDoux for his diligent work on this
-      feature!
-
-***** chkstow now honours the $STOW_DIR environment variable
-
-      The stow script already honoured the $STOW_DIR environment
-      variable.  Now chkstow does too, for consistency.
-
-***** Stow now has a non-zero exit code if option parsing failed
-
-      Thanks to Brice Waegeneire for reporting this.
-
-*** License upgraded from GPL version 2 to version 3
-
-    Copyright and license notices were also added to the headers of
-    various files in accordance with GNU guidelines.
-
-*** Documentation fixes and enhancements
-
-***** Remove dependency on unmaintained texi2html
-
-      The dependency on the ancient and unmaintained texi2html for
-      building the single-page HTML version of the manual has been
-      removed, since it was difficult to get running on most distros
-      other than openSUSE.
-
-      Instead use the more modern "makeinfo --html --no-split" approach.
-      Rules have been kept for posterity in the Makefile for the old
-      approach and also an "in-between" approach based on texi2any;
-      however these are not triggered by default.  Run
-
-         make manual-single-html-all
-
-      to compare the three versions.
-
-***** Fixed naming of man page
-
-      The title of the generated man page was previously ending up as
-      something like:
-
-         IO::FILE=IO(0XA719C0)(1)
-
-      Thanks to @Corin-EU on GitHub highlighting this and proposing a
-      fix.
-
-***** Convert README and INSTALL to Markdown
-
-      They are now named README.md and INSTALL.md, and render nicely
-      when viewed via git hosting services which support Markdown.
-
-***** Update documentation to reflect more modern use cases
-
-      The README.md, stow(8) man page, and info manual have been updated
-      to de-emphasise the package management use, since these days almost
-      everyone prefers to use modern package managers such as rpm / dpkg
-      / Nix for (system-wide) package management.
-
-      To compensate, more popular modern use cases for Stow have been
-      added, such as management of dotfiles and software compiled in the
-      user's $HOME directory.
-
-***** Miscellaneous documentation fixes
-
-      - Various typos were fixed.
-
-      - The documentation for --verbose was updated to indicate that
-        verbosity levels now go up to 5.
-
-      - Erroneous glob examples in the --ignore documentation were fixed.
-
-      - The abbreviation "regex" was removed from the info manual for
-        consistency.
-
-      - INSTALL.md now also documents how to build directly from git.
-
-*** Fixes for bugs, tests, and other technical debt
-
-***** Add Docker files for convenient testing across multiple Perl versions
-
-      This is the first release which has been tested across 5 different
-      versions of Perl prior to release!  The versions are:
-
-           perl-5.22.2
-           perl-5.20.3
-           perl-5.18.4
-           perl-5.16.3
-           perl-5.14.4
-
-      Thanks to Charles LeDoux for this!
-
-***** Set up continuous testing via Travis CI
-
-      This means that the test suite will be automatically run on any
-      pull requests submitted to GitHub, as well as "make distcheck"
-      and "./Build distcheck".
-
-***** Add Coveralls integration with GitHub
-
-      This means that test coverage analysis will be automatically be run
-      on any pull requests submitted to GitHub.
-
-***** Miscellaneous improvements to the test suite
-
-      These include proper testing of the distinct impact of ~/.stowrc
-      and .stowrc in the directory from which Stow is invoked.
-
-***** Fix for test suite on Cygwin
-
-      Thanks to Lucas Theisen for this fix!
-
-***** aclocal.m4 was updated using aclocal 1.15.1.
-
-***** Miscellaneous fixes to the build and distribution process
-
-***** Improve handling of directories with unusual names
-
-      Various fixes for corner cases where directories are named "0"
-      or begin with a space character, or where STOW_DIR is empty.
-
-      Thanks to Cuong Manh Le for highlighting some of the issues and
-      proposing fixes!
-
-* Changes in version 2.2.2
-
-*** @VERSION@ substitution was set up for the Stow::Util module.
-
-* Changes in version 2.2.1
-
-Version 2.2.1 was not released since it was rejected by pause.perl.org
-due to Stow::Util missing $VERSION.
-
-*** Small improvements to documentation
-
-***** The README has been revamped.
-
-***** Some index points have been added to the manual.
-
-***** Some typos were fixed.
-
-***** @VERSION@ substitution was fixed in the stow(8) man page.
-
-*** Fix Perl warnings
-
-    Stow no longer emits "v-string in use/require non-portable" and
-    "Possible precedence issue with control flow operator" warnings
-    with newer Perl versions.  See https://savannah.gnu.org/bugs/?36478
-    and http://lists.gnu.org/archive/html/bug-stow/2014-06/msg00000.html
-    for full details.
-
-*** Fix "Undefined subroutine &main::error" error
-
-    See https://rt.cpan.org/Public/Bug/Display.html?id=75349 for details.
-
-*** Failed system calls now include error description
-
-    This should make errors easier to understand.
-
-*** Default ignore list now ignores top-level README.*, LICENSE.*, and COPYING
-
-    These files are by definition specific to a given package, so if
-    they exist in the top-level directory, they should not be stowed.
-
-*** Correctly handle the stow/target directories as non-canonical paths
-
-    Fix the case discovered by Hiroyuki Iwatsuki where stowing fails if
-    the stow / target directories are non-canonical paths.  For
-    example, on FreeBSD /home is a symlink pointing to 'usr/home', so
-    running with the stow directory as /home/user/local/stow and the
-    target directory as /home/user/local previously resulted in the
-    stow directory path being calculated as
-    ../../../usr/home/user/local/stow relative to the target.
-
-    See https://lists.gnu.org/archive/html/bug-stow/2013-04/msg00000.html for details.
-
-*** Fix stowing of relative links when --no-folding is used.
-
-    With a tree like this:
-
-        .
-        |-- stow
-        |   `-- pkg
-        |       `-- lib
-        |           |-- itk-current -> itk4.0.0
-        |           `-- itk4.0.0
-        |               `-- libitk4.0.0.so
-        `-- target
-            `-- lib
-                |-- itk4.0.0 -> ../../stow/pkg/lib/itk4.0.0
-                `-- libfoo-1.2.3.so
-
-    stowing pkg with the --no-folding option resulted in itk-current
-    being "unpacked":
-
-        .
-        `-- target
-            `-- lib
-                |-- itk-current
-                |   `-- libitk4.0.0.so -> ../../../stow/pkg/lib/itk-current/libitk4.0.0.so
-                |-- itk4.0.0
-                |   `-- libitk4.0.0.so -> ../../../stow/pkg/lib/itk4.0.0/libitk4.0.0.so
-                `-- libfoo-1.2.3.so
-
-    This commit fixes it so that it gets stowed as a symlink:
-
-      .
-      `-- target
-          `-- lib
-              ...
-              |-- itk-current -> ../../stow/pkg/lib/itk-current
-              ...
-
-    Thanks to Gabriele Balducci for reporting this problem:
-
-        https://lists.gnu.org/archive/html/help-stow/2014-09/msg00000.html
-
-*** Internal code cleanups
-
-***** aclocal was updated.
-
-***** automake files were removed.
-
-***** Trailing whitespace was removed.
-
-***** Comments were added.
-
-***** Debug messages were improved.
-
-* Changes in version 2.2.0
-
-*** New --no-folding option
-
-    Disables folding of newly stowed directories when stowing, and
-    refolding of newly foldable directories when unstowing.
-
-*** Remove -a option (--adopt still available)
-
-    As --adopt is the only option which allows stow to modify files, it
-    is considered potentially dangerous (especially for stow package
-    directories which are not managed by a version control system).
-    Therefore it seems prudent to require a bit more effort from the
-    user to enable this option, minimising the change of enabling it
-    via a typo.
-
-*** Improve error message when stow package is not found.
-
-    The error message displayed a path to the missing stow package
-    which was relative to the target directory rather than the cwd,
-    which was confusing for the user.
-
-*** Test suite improvements
-
-    The test suite has been tightened up slightly.
-

-README for GNU Stow
-===================
-
-This README describes GNU Stow.  This is not the definitive
-documentation for Stow; for that, see the [info
-manual](https://www.gnu.org/software/stow/manual/).
-
-Stow is a symlink farm manager program which takes distinct sets
-of software and/or data located in separate directories on the
-filesystem, and makes them all appear to be installed in a single
-directory tree.
-
-Originally Stow was born to address the need to administer, upgrade,
-install, and remove files in independent software packages without
-confusing them with other files sharing the same file system space.
-For instance, many years ago it used to be common to compile programs
-such as Perl and Emacs from source and install them in `/usr/local`.
-By using Stow, `/usr/local/bin` could contain symlinks to files within
-`/usr/local/stow/emacs/bin`, `/usr/local/stow/perl/bin` etc., and
-likewise recursively for any other subdirectories such as `.../share`,
-`.../man`, and so on.
-
-While this is useful for keeping track of system-wide and per-user
-installations of software built from source, in more recent times
-software packages are often managed by more sophisticated package
-management software such as
-[`rpm`](https://en.wikipedia.org/wiki/Rpm_(software)),
-[`dpkg`](https://en.wikipedia.org/wiki/Dpkg), and
-[Nix](https://en.wikipedia.org/wiki/Nix_package_manager) / [GNU
-Guix](https://en.wikipedia.org/wiki/GNU_Guix), or language-native
-package managers such as Ruby's
-[`gem`](https://en.wikipedia.org/wiki/RubyGems), Python's
-[`pip`](https://en.wikipedia.org/wiki/Pip_(package_manager)),
-Javascript's [`npm`](https://en.wikipedia.org/wiki/Npm_(software)),
-and so on.
-
-However Stow is still used not only for software package management,
-but also for other purposes, such as facilitating [a more controlled
-approach to management of configuration files in the user's home
-directory](http://brandon.invergo.net/news/2012-05-26-using-gnu-stow-to-manage-your-dotfiles.html),
-especially when [coupled with version control
-systems](http://lists.gnu.org/archive/html/info-stow/2011-12/msg00000.html).
-
-Stow was inspired by Carnegie Mellon's Depot program, but is
-substantially simpler and safer.  Whereas Depot required database files
-to keep things in sync, Stow stores no extra state between runs, so
-there's no danger (as there was in Depot) of mangling directories when
-file hierarchies don't match the database.  Also unlike Depot, Stow will
-never delete any files, directories, or links that appear in a Stow
-directory (e.g., `/usr/local/stow/emacs`), so it's always possible
-to rebuild the target tree (e.g., `/usr/local`).
-
-Stow is implemented as a combination of a Perl script providing a CLI
-interface, and a backend Perl module which does most of the work.
-
-You can get the latest information about Stow from the home page:
-
-    http://www.gnu.org/software/stow/
-
-Installation
-------------
-
-See [`INSTALL.md`](INSTALL.md) for installation instructions.
-
-Documentation
--------------
-
-Documentation for Stow is available
-[online](https://www.gnu.org/software/stow/manual/), as is
-[documentation for most GNU
-software](https://www.gnu.org/software/manual/).  Once you have Stow
-installed, you may also find more information about Stow by running
-`info stow` or `man stow`, or by looking at `/usr/share/doc/stow/`,
-`/usr/local/doc/stow/`, or similar directories on your system.  A
-brief summary is available by running `stow --help`.
-
-Mailing lists
--------------
-
-Stow has the following mailing lists:
-
--   [help-stow](https://lists.gnu.org/mailman/listinfo/help-stow) is for
-    general user help and discussion.
--   [stow-devel](https://lists.gnu.org/mailman/listinfo/stow-devel) is
-    used to discuss most aspects of Stow, including development and
-    enhancement requests.
--   [bug-stow](https://lists.gnu.org/mailman/listinfo/bug-stow) is for
-    bug reports.
-
-Announcements about Stow are posted to
-[info-stow](http://lists.gnu.org/mailman/listinfo/info-stow) and also,
-as with most other GNU software, to
-[info-gnu](http://lists.gnu.org/mailman/listinfo/info-gnu)
-([archive](http://lists.gnu.org/archive/html/info-gnu/)).
-
-Security reports that should not be made immediately public can be
-sent directly to the maintainer.  If there is no response to an urgent
-issue, you can escalate to the general
-[security](http://lists.gnu.org/mailman/listinfo/security) mailing
-list for advice.
-
-The Savannah project also has a [mailing
-lists](https://savannah.gnu.org/mail/?group=stow) page.

-stow - manage farms of symbolic links
-
-=head1 SYNOPSIS
-
-stow [ options ] package ...
-
-=head1 DESCRIPTION
-
-This manual page describes GNU Stow @VERSION@.  This is not the
-definitive documentation for Stow; for that, see the accompanying info
-manual, e.g. by typing C<info stow>.
-
-Stow is a symlink farm manager which takes distinct sets of software
-and/or data located in separate directories on the filesystem, and
-makes them all appear to be installed in a single directory tree.
-
-Originally Stow was born to address the need to administer, upgrade,
-install, and remove files in independent software packages without
-confusing them with other files sharing the same file system space.
-For instance, many years ago it used to be common to compile programs
-such as Perl and Emacs from source.  By using Stow, F</usr/local/bin>
-could contain symlinks to files within F</usr/local/stow/emacs/bin>,
-F</usr/local/stow/perl/bin> etc., and likewise recursively for any
-other subdirectories such as F<.../share>, F<.../man>, and so on.
-
-While this is useful for keeping track of system-wide and per-user
-installations of software built from source, in more recent times
-software packages are often managed by more sophisticated package
-management software such as rpm, dpkg, and Nix / GNU Guix, or
-language-native package managers such as Ruby's gem, Python's pip,
-Javascript's npm, and so on.
-
-However Stow is still used not only for software package management,
-but also for other purposes, such as facilitating a more controlled
-approach to management of configuration files in the user's home
-directory, especially when coupled with version control systems.
-
-Stow was inspired by Carnegie Mellon's Depot program, but is
-substantially simpler and safer. Whereas Depot required database files
-to keep things in sync, Stow stores no extra state between runs, so
-there's no danger (as there was in Depot) of mangling directories when
-file hierarchies don't match the database. Also unlike Depot, Stow
-will never delete any files, directories, or links that appear in a
-Stow directory (e.g., F</usr/local/stow/emacs>), so it's always
-possible to rebuild the target tree (e.g., F</usr/local>).
-
-Stow is implemented as a combination of a Perl script providing a CLI
-interface, and a backend Perl module which does most of the work.
-
-=head1 TERMINOLOGY
-
-A "package" is a related collection of files and directories that
-you wish to administer as a unit -- e.g., Perl or Emacs -- and that
-needs to be installed in a particular directory structure -- e.g.,
-with F<bin>, F<lib>, and F<man> subdirectories.
-
-A "target directory" is the root of a tree in which one or more
-packages wish to B<appear> to be installed. A common, but by no means
-the only such location is F</usr/local>.  The examples in this manual
-page will use F</usr/local> as the target directory.
-
-A "stow directory" is the root of a tree containing separate
-packages in private subtrees. When Stow runs, it uses the current
-directory as the default stow directory. The examples in this manual
-page will use F</usr/local/stow> as the stow directory, so that
-individual packages will be, for example, F</usr/local/stow/perl> and
-F</usr/local/stow/emacs>.
-
-An "installation image" is the layout of files and directories
-required by a package, relative to the target directory. Thus, the
-installation image for Perl includes: a F<bin> directory containing
-F<perl> and F<a2p> (among others); an F<info> directory containing
-Texinfo documentation; a F<lib/perl> directory containing Perl
-libraries; and a F<man/man1> directory containing man pages.
-
-A "package directory" is the root of a tree containing the
-installation image for a particular package. Each package directory
-must reside in a stow directory -- e.g., the package directory
-F</usr/local/stow/perl> must reside in the stow directory
-F</usr/local/stow>.  The "name" of a package is the name of its
-directory within the stow directory -- e.g., F<perl>.
-
-Thus, the Perl executable might reside in
-F</usr/local/stow/perl/bin/perl>, where F</usr/local> is the target
-directory, F</usr/local/stow> is the stow directory,
-F</usr/local/stow/perl> is the package directory, and F<bin/perl>
-within is part of the installation image.
-
-A "symlink" is a symbolic link. A symlink can be "relative" or
-"absolute". An absolute symlink names a full path; that is, one
-starting from F</>.  A relative symlink names a relative path; that
-is, one not starting from F</>.  The target of a relative symlink is
-computed starting from the symlink's own directory.  Stow only creates
-relative symlinks.
-
-=head1 OPTIONS
-
-The stow directory is assumed to be the value of the C<STOW_DIR>
-environment variable or if unset the current directory, and the target
-directory is assumed to be the parent of the current directory (so it
-is typical to execute F<stow> from the directory F</usr/local/stow>).
-Each F<package> given on the command line is the name of a package in
-the stow directory (e.g., F<perl>).  By default, they are installed
-into the target directory (but they can be deleted instead using
-C<-D>).

-
-=item --stow
-
-Stow the packages that follow this option into the target directory.

-
-=item -D
-
-=item --delete
-
-Unstow the packages that follow this option from the target directory rather
-than installing them.
-
-=item -R
-
-=item --restow
-
-Restow packages (first unstow, then stow again). This is useful
-for pruning obsolete symlinks from the target tree after updating
-the software in a package.
-
-=item --adopt
-
-B<Warning!>  This behaviour is specifically intended to alter the
-contents of your stow directory.  If you do not want that, this option
-is not for you.
-
-When stowing, if a target is encountered which already exists but is a
-plain file (and hence not owned by any existing stow package), then
-normally Stow will register this as a conflict and refuse to proceed.
-This option changes that behaviour so that the file is moved to the
-same relative place within the package's installation image within the
-stow directory, and then stowing proceeds as before.  So effectively,
-the file becomes adopted by the stow package, without its contents
-changing.
-
-=item --no-folding
-
-Disable folding of newly stowed directories when stowing, and
-refolding of newly foldable directories when unstowing.
-
-=item --ignore=REGEX
-
-Ignore files ending in this Perl regex.
-
-=item --defer=REGEX
-
-Don't stow files beginning with this Perl regex if the file is already
-stowed to another package.
-
-=item --override=REGEX
-
-Force stowing files beginning with this Perl regex if the file is
-already stowed to another package.
-
-=item --dotfiles
-
-Enable special handling for "dotfiles" (files or folders whose name
-begins with a period) in the package directory. If this option is
-enabled, Stow will add a preprocessing step for each file or folder
-whose name begins with "dot-", and replace the "dot-" prefix in the
-name by a period (.). This is useful when Stow is used to manage
-collections of dotfiles, to avoid having a package directory full of
-hidden files.
-
-For example, suppose we have a package containing two files,
-F<stow/dot-bashrc> and F<stow/dot-emacs.d/init.el>. With this option,
-Stow will create symlinks from F<.bashrc> to F<stow/dot-bashrc> and
-from F<.emacs.d/init.el> to F<stow/dot-emacs.d/init.el>. Any other
-files, whose name does not begin with "dot-", will be processed as usual.

-
-=head1 INSTALLING PACKAGES
-
-The default action of Stow is to install a package. This means
-creating symlinks in the target tree that point into the package tree.
-Stow attempts to do this with as few symlinks as possible; in other
-words, if Stow can create a single symlink that points to an entire
-subtree within the package tree, it will choose to do that rather than
-create a directory in the target tree and populate it with symlinks.
-
-For example, suppose that no packages have yet been installed in
-F</usr/local>; it's completely empty (except for the F<stow>
-subdirectory, of course). Now suppose the Perl package is installed.
-Recall that it includes the following directories in its installation
-image: F<bin>; F<info>; F<lib/perl>; F<man/man1>.  Rather than
-creating the directory F</usr/local/bin> and populating it with
-symlinks to F<../stow/perl/bin/perl> and F<../stow/perl/bin/a2p> (and
-so on), Stow will create a single symlink, F</usr/local/bin>, which
-points to F<stow/perl/bin>.  In this way, it still works to refer to
-F</usr/local/bin/perl> and F</usr/local/bin/a2p>, and fewer symlinks
-have been created. This is called "tree folding", since an entire
-subtree is "folded" into a single symlink.
-
-To complete this example, Stow will also create the symlink
-F</usr/local/info> pointing to F<stow/perl/info>; the symlink
-F</usr/local/lib> pointing to F<stow/perl/lib>; and the symlink
-F</usr/local/man> pointing to F<stow/perl/man>.
-
-Now suppose that instead of installing the Perl package into an empty
-target tree, the target tree is not empty to begin with. Instead, it
-contains several files and directories installed under a different
-system-administration philosophy. In particular, F</usr/local/bin>
-already exists and is a directory, as are F</usr/local/lib> and
-F</usr/local/man/man1>.  In this case, Stow will descend into
-F</usr/local/bin> and create symlinks to F<../stow/perl/bin/perl> and
-F<../stow/perl/bin/a2p> (etc.), and it will descend into
-F</usr/local/lib> and create the tree-folding symlink F<perl> pointing
-to F<../stow/perl/lib/perl>, and so on. As a rule, Stow only descends
-as far as necessary into the target tree when it can create a
-tree-folding symlink.
-
-The time often comes when a tree-folding symlink has to be undone
-because another package uses one or more of the folded subdirectories
-in its installation image. This operation is called "splitting open"
-a folded tree. It involves removing the original symlink from the
-target tree, creating a true directory in its place, and then
-populating the new directory with symlinks to the newly-installed
-package B<and> to the old package that used the old symlink. For
-example, suppose that after installing Perl into an empty
-F</usr/local>, we wish to install Emacs.  Emacs's installation image
-includes a F<bin> directory containing the F<emacs> and F<etags>
-executables, among others. Stow must make these files appear to be
-installed in F</usr/local/bin>, but presently F</usr/local/bin> is a
-symlink to F<stow/perl/bin>.  Stow therefore takes the following
-steps: the symlink F</usr/local/bin> is deleted; the directory
-F</usr/local/bin> is created; links are made from F</usr/local/bin> to
-F<../stow/emacs/bin/emacs> and F<../stow/emacs/bin/etags>; and links
-are made from F</usr/local/bin> to F<../stow/perl/bin/perl> and
-F<../stow/perl/bin/a2p>.
-
-When splitting open a folded tree, Stow makes sure that the symlink
-it is about to remove points inside a valid package in the current stow
-directory.
-
-=head2 Stow will never delete anything that it doesn't own.
-
-Stow "owns" everything living in the target tree that points into a
-package in the stow directory. Anything Stow owns, it can recompute if
-lost. Note that by this definition, Stow doesn't "own" anything
-B<in> the stow directory or in any of the packages.
-
-If Stow needs to create a directory or a symlink in the target tree
-and it cannot because that name is already in use and is not owned by
-Stow, then a conflict has arisen. See the "Conflicts" section in the
-info manual.
-
-=head1 DELETING PACKAGES
-
-When the C<-D> option is given, the action of Stow is to delete a
-package from the target tree. Note that Stow will not delete anything
-it doesn't "own". Deleting a package does B<not> mean removing it from
-the stow directory or discarding the package tree.
-
-To delete a package, Stow recursively scans the target tree, skipping
-over the stow directory (since that is usually a subdirectory of the
-target tree) and any other stow directories it encounters (see
-"Multiple stow directories" in the info manual). Any symlink it
-finds that points into the package being deleted is removed. Any
-directory that contained only symlinks to the package being deleted is
-removed. Any directory that, after removing symlinks and empty
-subdirectories, contains only symlinks to a single other package, is
-considered to be a previously "folded" tree that was "split open."
-Stow will re-fold the tree by removing the symlinks to the surviving
-package, removing the directory, then linking the directory back to
-the surviving package.
-
-=head1 RESOURCE FILES
-
-F<Stow> searches for default command line options at F<.stowrc> (current
-directory) and F<~/.stowrc> (home directory) in that order. If both
-locations are present, the files are effectively appended together.
-
-The effect of options in the resource file is similar to simply prepending
-the options to the command line. For options that provide a single value,
-such as F<--target> or F<--dir>, the command line option will overwrite any
-options in the resource file. For options that can be given more than once,
-F<--ignore> for example, command line options and resource options are
-appended together.
-
-Environment variables and the tilde character (F<~>) will be expanded for
-options that take a file path.
-
-The options F<-D>, F<-R>, F<-S>, and any packages listed in the resource
-file are ignored.
-
-See the info manual for more information on how stow handles resource
-file.
-
-=head1 SEE ALSO
-
-The full documentation for F<stow> is maintained as a Texinfo manual.
-If the F<info> and F<stow> programs are properly installed at your site, the command
-
-    info stow
-
-should give you access to the complete manual.
-
-=head1 BUGS
-
-Please report bugs in Stow using the Debian bug tracking system.
-
-Currently known bugs include:
-
-=over 4
-
-=item * The empty-directory problem.
-
-If package F<foo> includes an empty directory -- say, F<foo/bar> --
-then if no other package has a F<bar> subdirectory, everything's fine.
-If another stowed package F<quux>, has a F<bar> subdirectory, then
-when stowing, F<targetdir/bar> will be "split open" and the contents
-of F<quux/bar> will be individually stowed.  So far, so good. But when
-unstowing F<quux>, F<targetdir/bar> will be removed, even though
-F<foo/bar> needs it to remain.  A workaround for this problem is to
-create a file in F<foo/bar> as a placeholder. If you name that file
-F<.placeholder>, it will be easy to find and remove such files when
-this bug is fixed.
-
-=item *
-
-When using multiple stow directories (see "Multiple stow directories"
-in the info manual), Stow fails to "split open" tree-folding symlinks
-(see "Installing packages" in the info manual) that point into a stow
-directory which is not the one in use by the current Stow
-command. Before failing, it should search the target of the link to
-see whether any element of the path contains a F<.stow> file. If it
-finds one, it can "learn" about the cooperating stow directory to
-short-circuit the F<.stow> search the next time it encounters a
-tree-folding symlink.

-How to make a new release of GNU Stow
-=====================================
-
-Prerequisite reading
---------------------
-
-First read the official information for maintainers of GNU software:
-
-  https://www.gnu.org/prep/maintain/
-
-Release procedure
------------------
-
-- Ensure configure.ac contains the number of the new unreleased
-  version.  This should follow Semantic Versioning as described at:
-
-    http://semver.org/
-
-- To make the following steps easier, set the $version shell variable
-  to the same version number as above, e.g.
-
-    version=$( tools/get-version ) && echo $version
-
-- Ensure NEWS contains the latest changes.  If necessary, commit
-  any additions:
-
-    git commit -m "Prepare NEWS for $version release"
-
-- Check CPAN distribution will work via Module::Build:
-
-    - Start from a clean slate:
-
-        make maintainer-clean
-        autoreconf -iv
-
-    - Generate stow, chkstow, and lib/Stow.pm via:
-
-        eval `perl -V:siteprefix`
-        automake --add-missing
-        ./configure --prefix=$siteprefix && make
-
-      (N.B. the CPAN distribution will contain these files, whereas
-      the GNU distribution will not.)
-
-    - Make sure all the following commands all run successfully:
-
-        perl Build.PL --prefix=/tmp/stow-test
-        ./Build test
-        ./Build install
-        ./Build distcheck
-        ./Build distmeta
-        ./Build dist
-
-    - Check META.yml and META.json have the new version number.
-      They already should if the final step of this document was
-      carried out after the previous release was publised, but
-      if not:
-
-        git commit -m "Bump version to $version"
-
-- Ensure all changes are committed to git.
-
-- Run make distcheck and ensure that everything looks good.
-  It should generate the distribution files for you.
-
-- Run the tests on various Perl versions via Docker:
-
-    ./build-docker.sh
-    ./test-docker.sh
-
-  Obviously if there are any failures, they will need to be fixed
-  first, and then repeat the above steps.
-
-- At this point we have a release candidate.  Tag the current git HEAD
-  with the new version number:
-
-    git tag -s v$version -m "Release $version"
-
-- Upload the resulting Stow-v7.8.9.tar.gz to CPAN via https://pause.perl.org/
-
-- Wait until PAUSE has accepted the upload as a valid module.  If you
-  are the maintainer of the module, you should receive two email
-  notifications: a CPAN upload confirmation, and a PAUSE indexer
-  report.  This provides some valuable final validation, as learnt the
-  hard way during the non-release of 2.2.1.
-
-- Push HEAD and tag to savannah and GitHub:
-
-    git push savannah master
-    git push --tags savannah
-    git push github master
-    git push --tags github
-
-- Upload the new release to ftp.gnu.org.  This is easiest using gnupload:
-
-    - git clone git://git.savannah.gnu.org/gnulib.git
-    - Copy gnulib/build-aux/gnupload to somewhere on your $PATH
-    - Run gnupload --to ftp.gnu.org:stow --symlink-regex stow-7.8.9.tar.*
-
-- Regenerate the documentation for the website:
-
-    # First check out gnulib repository via:
-    # git clone git://git.savannah.gnu.org/gnulib.git
-
-    # and stow-web CVS repository via the instructions here:
-    # https://savannah.gnu.org/cvs/?group=stow
-
-    # Set paths:
-    stow_repo=/path/to/stow/git/repo
-    stow_web_repo=/path/to/stow-web/CVS/working/dir
-    gnulib_repo=/path/to/gnulib/git/repo
-
-    cd $stow_repo
-    export GENDOCS_TEMPLATE_DIR=$gnulib_repo/doc
-    $gnulib_repo/util/gendocs.sh \
-        -s doc/stow.texi \
-        -o $stow_web_repo/manual \
-        --email bug-stow@gnu.org \
-        stow "GNU Stow manual"
-
-    cd $stow_web_repo
-    # Check that the changes look OK
-    cvs diff
-    # Then commit
-    cvs commit -m "Update manual to v$version"
-
-- Update the news section of stow.html in the stow-web CVS repository
-  to mention the new release.
-
-    cd $stow_web_repo
-    # Check that the changes look OK
-    cvs diff
-    # Then commit
-    cvs commit -m "Update home page to v$version"
-
-- Send release announcements to
-
-    - info-stow@gnu.org
-    - stow-devel@gnu.org
-    - info-gnu@gnu.org
-    - https://savannah.gnu.org/news/?group=stow
-
-  See http://www.gnu.org/prep/maintain/html_node/Announcements.html for
-  more on making release announcements.
-
-  Excerpts of NEWS can be formatted for inclusion in the email by
-  selecting the relevant version subtree via M-x org-mark-element,
-  minus the "* Changes in version x.y.z", running M-x
-  org-export-dispatch, and exporting as plain text.
-
-- Update the git repositories to the next expected version, so that anyone
-  who builds from git gets a version of Stow which is higher than the release
-  which was just cut:
-
-    - Increment the patchlevel of the version number in configure.ac.
-
-    - Run this again:
-
-        version=$( tools/get-version ) && echo $version
-
-    - In order to update META.yml and META.json, repeat the same
-      procedure listed above, starting at "make distclean" and
-      finishing after "./Build distmeta".
-
-    - Check META.yml and META.json now have the new versions.
-
-    - git add configure.ac META.{yml,json}
-
-    - git commit -m "Bump version to $version for development of next release"
-
-    - git push savannah master
-
-    - git push github master

+.SH NAME
+stow \- software package installation manager
+.SH SYNOPSIS
+.B stow
+.RI [ options ]
+.IR package ...
+.SH DESCRIPTION
+This manual page describes GNU Stow 1.3.3, a program for managing the
+installation of software packages. This is not the definitive
+documentation for stow; for that, see the info manual.
+.PP
+Stow is a tool for managing the installation of multiple software
+packages in the same run-time directory tree. One historical difficulty
+of this task has been the need to administer, upgrade, install, and
+remove files in independent packages without confusing them with other
+files sharing the same filesystem space. For instance, it is common to
+install Perl and Emacs in
+.IR /usr/local .
+When one does so, one winds up
+(as of Perl 4.036 and Emacs 19.22)
+with the following files in
+.IR /usr/local/man/man1 :
+.IR a2p.1 ;
+.IR ctags.1 ;
+.IR emacs.1 ;
+.IR etags.1 ;
+.IR h2ph.1 ;
+.IR perl.1 ;
+and
+.IR s2p.1 .
+Now
+suppose it's time to uninstall Perl. Which man pages get removed?
+Obviously
+.I perl.1
+is one of them, but it should not be the
+administrator's responsibility to memorize the ownership of individual
+files by separate packages.
+.PP
+The approach used by Stow is to install each package into its own
+tree, then use symbolic links to make it appear as though the files are
+installed in the common tree. Administration can be performed in the
+package's private tree in isolation from clutter from other packages.
+Stow can then be used to update the symbolic links. The structure of
+each private tree should reflect the desired structure in the common
+tree; i.e. (in the typical case) there should be a
+.I bin
+directory
+containing executables, a
+.I man/man1
+directory containing section 1 man
+pages, and so on.
+.PP
+Stow was inspired by Carnegie Mellon's Depot program, but is
+substantially simpler and safer. Whereas Depot required database files
+to keep things in sync, Stow stores no extra state between runs, so
+there's no danger (as there was in Depot) of mangling directories when
+file hierarchies don't match the database. Also unlike Depot, Stow will
+never delete any files, directories, or links that appear in a Stow
+directory (e.g.,
+.IR /usr/local/stow/emacs ),
+so it's always possible to
+rebuild the target tree (e.g.,
+.IR /usr/local ).
+.SH TERMINOLOGY
+A ``package'' is a related collection of files and directories that
+you wish to administer as a unit--e.g., Perl or Emacs--and that needs
+to be installed in a particular directory structure--e.g., with
+.IR bin ,
+.IR lib ,
+and
+.I man
+subdirectories.
+.PP
+A ``target directory'' is the root of a tree in which one or more
+packages wish to
+.B appear
+to be installed. A common, but by no means
+the only such location is
+.IR /usr/local .
+The examples in this manual page
+will use
+.I /usr/local
+as the target directory.
+.PP
+A ``stow directory'' is the root of a tree containing separate
+packages in private subtrees. When Stow runs, it uses the current
+directory as the default stow directory. The examples in this manual
+page will use
+.I /usr/local/stow
+as the stow directory, so that individual
+packages will be, for example,
+.I /usr/local/stow/perl
+and
+.IR /usr/local/stow/emacs .
+.PP
+An ``installation image'' is the layout of files and directories
+required by a package, relative to the target directory. Thus, the
+installation image for Perl includes: a
+.I bin
+directory containing
+.I perl
+and
+.I a2p
+(among others); an
+.I info
+directory containing Texinfo
+documentation; a
+.I lib/perl
+directory containing Perl libraries; and a
+.I man/man1
+directory containing man pages.
+.PP
+A ``package directory'' is the root of a tree containing the
+installation image for a particular package. Each package directory
+must reside in a stow directory--e.g., the package directory
+.I /usr/local/stow/perl
+must reside in the stow directory
+.IR /usr/local/stow .
+The ``name'' of a package is the name of its
+directory within the stow directory--e.g.,
+.IR perl .
+.PP
+Thus, the Perl executable might reside in
+.IR /usr/local/stow/perl/bin/perl ,
+where
+.I /usr/local
+is the target
+directory,
+.I /usr/local/stow
+is the stow directory,
+.I /usr/local/stow/perl
+is the package directory, and
+.I bin/perl
+within
+is part of the installation image.
+.PP
+A ``symlink'' is a symbolic link. A symlink can be ``relative'' or
+``absolute''. An absolute symlink names a full path; that is, one
+starting from
+.IR / .
+A relative symlink names a relative path; that is,
+one not starting from
+.IR / .
+The target of a relative symlink is
+computed starting from the symlink's own directory. Stow only creates
+relative symlinks.
+.SH OPTIONS
+The stow directory is assumed to be the current directory, and the
+target directory is assumed to be the parent of the current directory
+(so it is typical to execute
+.I stow
+from the directory
+.IR /usr/local/stow ).
+Each
+.I package
+given on the command line is the name of a package in the stow
+directory (e.g.,
+.IR perl ).
+By default, they are installed into the
+target directory (but they can be deleted instead using `-D').
+.TP
+.I -n
+.TP
+.I --no
+Do not perform any operations that modify the filesystem; merely
+show what would happen. Since no actual operations are performed,
+.I stow -n
+could report conflicts when none would actually take
+place (see ``Conflicts'' in the info manual);
+but it won't fail to report conflicts
+that
+.B would
+take place.
+.TP
+.I -c
+.TP
+.I --conflicts
+Do not exit immediately when a conflict is encountered. This
+option implies `-n', and is used to search for all conflicts that
+might arise from an actual Stow operation. As with `-n', however,
+false conflicts might be reported (see ``Conflicts'' in the info manual).
+.TP
+.I "-d DIR"
+.TP
+.I --dir=DIR
+Set the stow directory to DIR instead of the current directory.
+This also has the effect of making the default target directory be
+the parent of DIR.
+.TP
+.I "-t DIR"
+.TP
+.I --target=DIR
+Set the target directory to DIR instead of the parent of the stow
+directory.
+.TP
+.I -v
+.TP
+.I --verbose[=N]
+Send verbose output to standard error describing what Stow is
+doing. Verbosity levels are 0, 1, 2, and 3; 0 is the default.
+Using `-v' or `--verbose' increases the verbosity by one; using
+`--verbose=N' sets it to N.
+.TP
+.I -D
+.TP
+.I --delete
+Delete packages from the target directory rather than installing
+them.
+.TP
+.I -R
+.TP
+.I --restow
+Restow packages (first unstow, then stow again). This is useful
+for pruning obsolete symlinks from the target tree after updating
+the software in a package.
+.TP
+.I -V
+.TP
+.I --version
+Show Stow version number, and exit.
+.TP
+.I -h
+.TP
+.I --help
+Show Stow command syntax, and exit.
+.SH "INSTALLING PACKAGES"
+The default action of Stow is to install a package. This means
+creating symlinks in the target tree that point into the package tree.
+Stow attempts to do this with as few symlinks as possible; in other
+words, if Stow can create a single symlink that points to an entire
+subtree within the package tree, it will choose to do that rather than
+create a directory in the target tree and populate it with symlinks.
+.PP
+For example, suppose that no packages have yet been installed in
+.IR /usr/local ;
+it's completely empty (except for the
+.I stow
+subdirectory, of course). Now suppose the Perl package is installed.
+Recall that it includes the following directories in its installation
+image:
+.IR bin ;
+.IR info ;
+.IR lib/perl ;
+.IR man/man1 .
+Rather than creating
+the directory
+.I /usr/local/bin
+and populating it with symlinks to
+.I ../stow/perl/bin/perl
+and
+.I ../stow/perl/bin/a2p
+(and so on), Stow
+will create a single symlink,
+.IR /usr/local/bin ,
+which points to
+.IR stow/perl/bin .
+In this way, it still works to refer to
+.I /usr/local/bin/perl
+and
+.IR /usr/local/bin/a2p ,
+and fewer symlinks have
+been created. This is called ``tree folding'', since an entire subtree
+is ``folded'' into a single symlink.
+.PP
+To complete this example, Stow will also create the symlink
+.I /usr/local/info
+pointing to
+.IR stow/perl/info ;
+the symlink
+.I /usr/local/lib
+pointing to
+.IR stow/perl/lib ;
+and the symlink
+.I /usr/local/man
+pointing to
+.IR stow/perl/man .
+.PP
+Now suppose that instead of installing the Perl package into an empty
+target tree, the target tree is not empty to begin with. Instead, it
+contains several files and directories installed under a different
+system-administration philosophy. In particular,
+.I /usr/local/bin
+already exists and is a directory, as are
+.I /usr/local/lib
+and
+.IR /usr/local/man/man1 .
+In this case, Stow will descend into
+.I /usr/local/bin
+and create symlinks to
+.I ../stow/perl/bin/perl
+and
+.I ../stow/perl/bin/a2p
+(etc.), and it will descend into
+.I /usr/local/lib
+and create the tree-folding symlink
+.I perl
+pointing to
+.IR ../stow/perl/lib/perl ,
+and so on. As a rule, Stow only descends as
+far as necessary into the target tree when it can create a tree-folding
+symlink.
+.PP
+The time often comes when a tree-folding symlink has to be undone
+because another package uses one or more of the folded subdirectories in
+its installation image. This operation is called ``splitting open'' a
+folded tree. It involves removing the original symlink from the target
+tree, creating a true directory in its place, and then populating the
+new directory with symlinks to the newly-installed package
+.B and
+to the
+old package that used the old symlink. For example, suppose that after
+installing Perl into an empty
+.IR /usr/local ,
+we wish to install Emacs.
+Emacs's installation image includes a
+.I bin
+directory containing the
+.I emacs
+and
+.I etags
+executables, among others. Stow must make these
+files appear to be installed in
+.IR /usr/local/bin ,
+but presently
+.I /usr/local/bin
+is a symlink to
+.IR stow/perl/bin .
+Stow therefore takes
+the following steps: the symlink
+.I /usr/local/bin
+is deleted; the
+directory
+.I /usr/local/bin
+is created; links are made from
+.I /usr/local/bin
+to
+.I ../stow/emacs/bin/emacs
+and
+.IR ../stow/emacs/bin/etags ;
+and links are made from
+.I /usr/local/bin
+to
+.I ../stow/perl/bin/perl
+and
+.IR ../stow/perl/bin/a2p .
+.PP
+When splitting open a folded tree, Stow makes sure that the symlink
+it is about to remove points inside a valid package in the current stow
+directory.
+.BR "Stow will never delete anything that it doesn't own" .
+Stow ``owns'' everything living in the target tree that points into a
+package in the stow directory. Anything Stow owns, it can recompute if
+lost. Note that by this definition, Stow doesn't ``own'' anything
+.B in
+the stow directory or in any of the packages.
+.PP
+If Stow needs to create a directory or a symlink in the target tree
+and it cannot because that name is already in use and is not owned by
+Stow, then a conflict has arisen. See ``Conflicts'' in the info manual.
+.SH "DELETING PACKAGES"
+When the `-D' option is given, the action of Stow is to delete a
+package from the target tree. Note that Stow will not delete anything
+it doesn't ``own''. Deleting a package does
+.B not
+mean removing it from
+the stow directory or discarding the package tree.
+.PP
+To delete a package, Stow recursively scans the target tree,
+skipping over the stow directory (since that is usually a subdirectory
+of the target tree) and any other stow directories it encounters (see
+``Multiple stow directories'' in the info manual). Any symlink it finds that points into
+the package being deleted is removed. Any directory that contained
+only symlinks to the package being deleted is removed. Any directory
+that, after removing symlinks and empty subdirectories, contains only
+symlinks to a single other package, is considered to be a previously
+``folded'' tree that was ``split open.'' Stow will re-fold the tree by
+removing the symlinks to the surviving package, removing the directory,
+then linking the directory back to the surviving package.
+.SH "SEE ALSO"
+The info manual ``Stow 1.3.3:
+Managing the installation of software packages''
+by Bob Glickstein, Zanshin Software, Inc.
+.SH BUGS
+Please report bugs in Stow using the Debian bug tracking system.
+.PP
+Currently known bugs include:
+.IP *
+The empty-directory problem. If package FOO includes an empty
+directory--say, FOO/BAR--then:
+.IP
+1.
+if no other package has a BAR subdirectory, everything's fine.
+.IP
+2.
+if another stowed package, QUUX, has a BAR subdirectory, then
+when stowing, TARGETDIR/BAR will be ``split open'' and the
+contents of QUUX/BAR will be individually stowed. So far, so
+good. But when unstowing QUUX, TARGETDIR/BAR will be
+removed, even though FOO/BAR needs it to remain. A
+workaround for this problem is to create a file in FOO/BAR as
+a placeholder. If you name that file
+.IR .placeholder ,
+it will
+be easy to find and remove such files when this bug is fixed.
+.IP *
+When using multiple stow directories (see ``Multiple stow
+directories'' in the info manual), Stow fails to ``split open'' tree-folding symlinks
+(see ``Installing packages'' in the info manual) that point into a stow directory
+which is not the one in use by the current Stow command. Before
+failing, it should search the target of the link to see whether
+any element of the path contains a
+.I .stow
+file. If it finds one,
+it can ``learn'' about the cooperating stow directory to
+short-circuit the
+.I .stow
+search the next time it encounters a
+tree-folding symlink.
