 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.
 Maintainers
 -----------
 Stow is currently being maintained by Adam Spiers.  Please use [the
 mailing lists](README.md#mailing-lists).

 News file for Stow.
 * Changes in version 2.4.0
 *** --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

 names a relative path; that is, one not starting from @file{/}.  The
 destination of a relative symlink is computed starting from the
 symlink's own directory, i.e.@: the directory containing the symlink
 source.
@quotation Note
 Stow only creates symlinks within the target directory which point to
 locations @emph{outside} the target directory and inside the stow
 directory.
 Consequently, we avoid referring to symlink destinations as symlink
@emph{targets}, since this would result in the word ``target'' having
 two different meanings:
@enumerate
@item
 the target directory, i.e.@: the directory into which Stow targets
 installation, where symlinks are managed by Stow, and
@item
 the destinations of those symlinks.
@end enumerate
 If we did not avoid the second meaning of ``target'', then it would lead
 to confusing language, such as describing Stow as installing symlinks
 into the target directory which point to targets @emph{outside} the
 target directory.
 Similarly, the word ``source'' can have two different meanings in this
 context:
@enumerate
@item
 the installation image, or some of its contents, and
@item
 the location of symlinks (the ``source'' of the link, vs.@: its
 destination).
@end enumerate
 Therefore it should also be avoided, or at least care taken to ensure
 that the meaning is not ambiguous.
