+ # Convenience script for regenerating all autogeneratable files that are
+ # omitted from the version control repository. In particular, this script
+ # also regenerates all aclocal.m4, config.h.in, Makefile.in, configure files
+ # with new versions of autoconf or automake.
+ #
+ # This script requires autoconf-2.63..2.69 and automake-1.11..1.16 in the PATH.
+ # If not used from a released tarball, it also requires either
+ #   - the GNULIB_SRCDIR environment variable pointing to a gnulib checkout, or
+ #   - a preceding invocation of './gitsub.sh pull'.
+ # It also requires
+ #   - the gperf program.

+ #
+ #   1) Its options are easy to remember, and do not require knowledge of
+ #      'git submodule'.
+ #
+ #   2) The developer may choose to work on a different checkout for each
+ #      dependency package.  This is important when the developer is
+ #      preparing simultaneous changes to the package and the dependency
+ #      package, or is using the dependency package in several packages.
+ #
+ #      The developer indicates this different checkout by setting the
+ #      environment variable <SUBDIR>_SRCDIR (e.g. GNULIB_SRCDIR) to point to it.
+ #
+ #   3) The package maintainer may choose to use or not use git submodules.
+ #
+ #      The advantages of management through a git submodule are:
+ #        - Changes to the dependency package cannot suddenly break your package.
+ #          In other words, when there is an incompatible change that will cause
+ #          a breakage, you can fix things at your pace; you are not forced to
+ #          cope with such breakages in an emergency.
+ #        - When you need to make a change as a response to a change in the
+ #          dependency package, your co-developers cannot accidentally mix things
+ #          up (for example, use a combination of your newest change with an
+ #          older version of the dependency package).
+ #
+ #      The advantages of management without a git submodule (just as a plain
+ #      subdirectory, let's call it a "subcheckout") are:
+ #        - The simplicity: you are conceptually always using the newest revision
+ #          of the dependency package.
+ #        - You don't have to remember to periodially upgrade the dependency.
+ #          Upgrading the dependency is an implicit operation.
+ 
+ # This program is meant to be copied to the top-level directory of the package,
+ # together with a configuration file.  The configuration is supposed to be
+ # named '.gitmodules' and to define:
+ # * The git submodules, as described in "man 5 gitmodules" or
+ #   <https://git-scm.com/docs/gitmodules>.  For example:
+ #
+ #       [submodule "gnulib"]
+ #               url = git://git.savannah.gnu.org/gnulib.git
+ #               path = gnulib
+ #
+ #   You don't add this piece of configuration to .gitmodules manually.  Instead,
+ #   you would invoke
+ #     $ git submodule add --name "gnulib" -- git://git.savannah.gnu.org/gnulib.git gnulib
+ #
+ # * The subdirectories that are not git submodules, in a similar syntax.  For
+ #   example:
+ #
+ #       [subcheckout "gnulib"]
+ #               url = git://git.savannah.gnu.org/gnulib.git
+ #               path = gnulib
+ #
+ # Here the URL is the one used for anonymous checkouts of the dependency
+ # package. If the developer needs a checkout with write access, they can
+ # either set the GNULIB_SRCDIR environment variable to point to that checkout
+ # or modify the gnulib/.git/config file to enter a different URL.

+ gitsub.sh upgrade [SUBDIR]
+         You should perform this operation periodically, to ensure currency
+         of the dependency package revisions that you use.
+         This operation pulls and checks out the changes that the developers
+         of the dependency package have committed and pushed.
+         If an environment variable <SUBDIR>_SRCDIR is set, with a non-empty

+         Checks out a specific revision for a dependency package.
+         If an environment variable <SUBDIR>_SRCDIR is set, with a non-empty
