Stow was written by Bob Glickstein <bobg+stow@zanshin.com>, Zanshin
Software, Inc.
Contributions from Gord Matzigkeit <gord@enci.ucalgary.ca>.
John Bazik wrote `fastcwd', the Perl subroutine for computing the
current working directory.
Charles Briscoe-Smith <cpbs@debian.org> wrote the fix to prevent
stow -D / stow -R removing initially-empty directories.
Adam Lackorzynski <al10@inf.tu-dresden.de> wrote the fix to prevente
the generation of wrong links if there are links in the stow directory.
Stow was maintained by Guillaume Morin <gmorin@gnu.org> up to November 2007.
Kahlil (Kal) Hodgson <kahlil@internode.on.net> performed a major rewrite
inorder to implement:
1. defered operations,
2. option parsing via Getopt::Long,
3. options to support shared files,
4. support for multiple operations per invocation,
5. default command line arguments via '.stowrc' and '~/.stowrc' files,
6. better cooperation between multiple stow directories,
7. a test suite (and support code) to ensure that everything still works.
As these changes required a dramatic reorganisation of the code, very little
was left untouched, and so stows major version was bumped up to version 2.
Austin Wood <austin.wood@rmit.edu.au> and Chris Hoobin
<christopher.hoobin@rmit.edu.au> helped clean up the documentation for
version 2 and created the texi2man script.
Stow is currently maintained by Kahlil (Kal) Hodgson <kahlil@internode.on.net>.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

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.

News file for Stow.
* Changes in version 2.0.1:
** Defer operations until all potential conflicts have been assessed.
We do this by traversing the installation image(s) and recording the
actions that need to be performed. Redundant actions are factored out,
e.g., we don't want to create a link that we will later remove in order to
create a directory. Benefits of this approach
1. Get to see _all_ the conflicts that are blocking an installation:
you don't have to deal with them one at a time.
2. No operations are be performed if _any_ conflicts are detected:
a failed stow will not leave you with a partially installed
package.
3. Minimises the set of operations that need to be performed.
4. Operations are executed as a batch which is much faster
This can be an advantage when upgrading packages on a live system
where you want to minimise the amount of time when the package is
unavailable.
** The above fixes the false conflict problem mentioned in the info file.
** It also fixes the two bugs mentioned in the man page.
** Multiple stow directories will now cooperate in folding/unfolding.
** Conflict messages are more uniform and informative.
** Verbosity and tracing is more extensive and uniform.
** Implemented option parsing via Getopt::Long.
** Default command line arguments set via '.stowrc' and '~/.stowrc' files.
Contents of these files are parsed as though they occurred first on the
command line.
** Support multiple actions per invocation.
In order for this to work, we had to add a new (optional) command line arg
(-S) to specify packages to stow. For example, to update an installation
of emacs you can now do
stow -D emacs-21.3 -S emacs-21.4a
which will replace emacs-21.3 with emacs-21.4a.
You can mix and match any number of actions, e.g.,
stow -S p1 p2 -D p3 p4 -S p5 -R p6
will unstow p3, p4 and p6, then stow p1, p2, p5 and p6.
* New (repeatable) command line arg: --ignore='<regex>'
This suppresses operating on a file matching the regex (suffix), e.g.,
--ignore='~' --ignore='\.#.*'
will ignore emacs and CVS backup files (suitable for ~/.stowrc file).
(I opted for Perl regular expressions because they are more powerful and
easier to implement).
** New (repeatable) command line arg: --defer='<regex>'
This defers stowing a file matching the regex (prefix) if that file is
already stowed to a different package, e.g.,
--defer='man' --defer='info'
will cause stow to skip over pre-existing man and info pages.
Equivalently, you could use --defer='man|info' since the argument is just
a Perl regex.
** New (repeatable) command line arg: --override='<regex>'
This forces a file matching the regex (prefix) to be stowed even if the
file is already stowed to a different package, e.g.,
--override='man' --override='info'
will unstow any pre-existing man and info pages that would conflict with
the file we are trying to stow.
Equivalently, you could use --override='man|info' since the argument is
just a Perl regex.
** The above gives the ability to manage packages with common content.
For example, man pages that are shared by a number of CPAN packages.
Using multiple stow directories and .stowrc files can also simplify
things. In our setup we use the standard /usr/local/stow directory for
packages to be installed in /usr/local. Since we install a large number
of extra Perl packages (currently about 300) we use an additional stow
directory: /usr/local/stow/perl-5.8.8-extras. Both stow directories
contain a '.stow' file so that they collaborate appropriately. I then use
the following .stowrc file in /usr/local/stow/perl-5.8.8-extras
--dir=/usr/local/stow/perl-5.8.8-extras
--target=/usr/local
--override=bin
--override=man
--ignore='perllocal\.pod'
--ignore='\.packlist'
--ignore='\.bs'
When I stow packages from there, they automatically override any man pages
and binaries that may already have been stowed by another package or by
the core perl-5.8.8 installation. For example, if you want to upgrade the
Test-Simple package, you need to override all the man pages that would
have been installed by the core package. If you are upgrading CPAN, you
will also have to override the pre-existing cpan executable.
** By default, search less aggressively for invalid symlinks when unstowing.
That is, we only search for bad symlinks in the directories explicitly
mentioned in the installation image, and do not dig down into other
subdirs. Digging down into other directories can be very time consuming
if you have a really big tree (like with a couple of Oracle installations
lying around). In general the old behaviour is only necessary when you
have really stuffed up your installation by deleting a directory that has
already been stowed. Doing that on a live system is somewhat crazy and
hopefully rare. We provide an option '-p|--compat' to enable the old
behaviour for those needing to patch up mistakes.
** Implement a test suite and support code.
This was built before implementing any of the extra features so I could
more easily check for equivalent functionality. The initial code base had
to be refactored substantially to allow for testing. The test suite is
not exhaustive, but it should provide enough to check for regressions.
* Changes in version 1.3.3:
** Now requires Perl 5.005 or later
** Initially empty directories are not removed anymore
** Removed buggy fastcwd (we use POSIX::getcwd instead)
** Fixed bug when the common Parent of Target dir and Stow dir was "/"
** Fixed bug when handling directories named "0"
** Stow now only warns the user if a directory is unreadable during unstowing.
* Changes in version 1.3:
** Added --restow option.
** Fixed handling of slashes in package names.
** Expanded configure-time search for Perl binary.
* Changes in version 1.2:
** Dependency on `pwd' removed.
** Perl 4 compatibility fixes.
** Manual expanded even more.
* Changes in version 1.1:
** Long and short options now accepted.
** Manual expanded.
** `make clean' removes stow (which is generated from stow.in).
* Initial public release (v1.0) of Stow.

This is GNU Stow, a program for managing the installation of software
packages, keeping them separate (/usr/local/stow/emacs vs.
/usr/local/stow/perl, for example) while making them appear to be installed in
the same place (/usr/local). Stow doesn't store an extra state between runs,
so there's no danger of mangling directories when file hierarchies don't match
the database. Also, stow will never delete any files, directories, or links
that appear in a stow directory, so it is always possible to rebuild the
target tree.
Stow is a Perl script which should run correctly under Perl 4 and Perl 5. You
must install Perl before running Stow. For more information about Perl, see
http://www.perl.com/perl/.
You can get the latest information about Stow from
http://www.gnu.org/software/stow/stow.html
Stow was inspired by Carnegie Mellon's "Depot" program, but is substantially
simpler. Whereas Depot requires database files to keep things in sync, Stow
stores no extra state between runs, so there's no danger (as there is 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 free software, licensed under the GNU General Public License, which
can be found in the file COPYING.
See INSTALL for installation instructions.
Please mail comments, questions, and criticisms to the current maintainer,
Kahlil (Kal) Hodgson via help-stow@gnu.org or bug-stow@gnu.org.

From e-mail with meyering@na-net.ornl.gov:
> My /usr/local/info equivalent is a symlink to /share/info
> because I want installs on all systems to put info files in that
> directory. With that set-up, stow chokes on fact that
> /usr/local/info is a symlink.
[...] Stow is designed to be paranoid about modifying anything it
doesn't "own." If it finds a symlink in the target tree (e.g.,
/usr/local/info) which doesn't point into the stow tree, its
paranoid response is to leave it the hell alone. But I can see in
this case how traversing the link and populating the directory on
the far end would be OK. Question: is that a special
circumstance, or would it always be OK to populate the far end of
a symlink in the target tree (when the symlink points to a
directory in a context where a directory is needed)? And: if it's
a special circumstance requiring a command-line option, should the
option be a mere boolean (such as, "--traverse-target-links") or
should it be an enumeration of which links are OK to traverse
(such as, "--traversable='info man doc'")?
Does Version 2 fix this? (Kal)
I think that because it never needs to create /usr/local/info,
it only needs to check th ownership of links that it _operatates_ on,
not on all the elements of the path.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#

# AM_PROG_INSTALL_STRIP
# ---------------------
# One issue with vendor `install' (even GNU) is that you can't
# specify the program used to strip binaries. This is especially
# annoying in cross-compiling environments, where the build's strip
# is unlikely to handle the host's binaries.
# Fortunately install-sh will honor a STRIPPROG variable, so we
# always use install-sh in `make install-strip', and initialize
# STRIPPROG with the value of the STRIP variable (set by the user).
AC_DEFUN([AM_PROG_INSTALL_STRIP],
[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
# Installed binaries are usually stripped using `strip' when the user
# run `make install-strip'. However `strip' might not be the right
# tool to use in cross-compilation environments, therefore Automake
# will honor the `STRIP' environment variable to overrule this program.
dnl Don't test for $cross_compiling = yes, because it might be `maybe'.

.TH STOW 8 "28 March 1998"
.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 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.
