227fa8417cSAndreas Gruenbacher# Originally written by Paul Eggert.  The canonical version of this
237fa8417cSAndreas Gruenbacher# script is maintained as build-aux/bootstrap in gnulib, however, to
247fa8417cSAndreas Gruenbacher# be useful to your project, you should place a copy of it under
257fa8417cSAndreas Gruenbacher# version control in the top-level directory of your project.  The
267fa8417cSAndreas Gruenbacher# intent is that all customization can be done with a bootstrap.conf
277fa8417cSAndreas Gruenbacher# file also maintained in your version control; gnulib comes with a
287fa8417cSAndreas Gruenbacher# template build-aux/bootstrap.conf to get you started.

557fa8417cSAndreas GruenbacherBootstrap this package from the checked-out sources.
567fa8417cSAndreas Gruenbacher
577fa8417cSAndreas GruenbacherOptions:
584a7efc37SJim Meyering --gnulib-srcdir=DIRNAME  specify the local directory where gnulib
597fa8417cSAndreas Gruenbacher                          sources reside.  Use this if you already
607fa8417cSAndreas Gruenbacher                          have gnulib sources on your machine, and
617fa8417cSAndreas Gruenbacher                          do not want to waste your bandwidth downloading
624a7efc37SJim Meyering                          them again.  Defaults to \$GNULIB_SRCDIR
634a7efc37SJim Meyering --bootstrap-sync         if this bootstrap script is not identical to
644a7efc37SJim Meyering                          the version in the local gnulib sources,
654a7efc37SJim Meyering                          update this script, and then restart it with
664a7efc37SJim Meyering                          /bin/sh or the shell \$CONFIG_SHELL
674a7efc37SJim Meyering --no-bootstrap-sync      do not check whether bootstrap is out of sync
684a7efc37SJim Meyering --copy                   copy files instead of creating symbolic links
694a7efc37SJim Meyering --force                  attempt to bootstrap even if the sources seem
704a7efc37SJim Meyering                          not to have been checked out
714a7efc37SJim Meyering --no-git                 do not use git to update gnulib.  Requires that
724a7efc37SJim Meyering                          --gnulib-srcdir point to a correct gnulib snapshot
734a7efc37SJim Meyering --skip-po                do not download po files
744a7efc37SJim Meyering
754a7efc37SJim MeyeringIf the file $me.conf exists in the same directory as this script, its
767fa8417cSAndreas Gruenbachercontents are read as shell variables to configure the bootstrap.

787fa8417cSAndreas GruenbacherFor build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
797fa8417cSAndreas Gruenbacherare honored.

8109939400SAndreas GruenbacherGnulib sources can be fetched in various ways:
8209939400SAndreas Gruenbacher
8309939400SAndreas Gruenbacher * If this package is in a git repository with a 'gnulib' submodule
8409939400SAndreas Gruenbacher   configured, then that submodule is initialized and updated and sources
8509939400SAndreas Gruenbacher   are fetched from there.  If \$GNULIB_SRCDIR is set (directly or via
8609939400SAndreas Gruenbacher   --gnulib-srcdir) and is a git repository, then it is used as a reference.
8709939400SAndreas Gruenbacher
8809939400SAndreas Gruenbacher * Otherwise, if \$GNULIB_SRCDIR is set (directly or via --gnulib-srcdir),
8909939400SAndreas Gruenbacher   then sources are fetched from that local directory.  If it is a git
9009939400SAndreas Gruenbacher   repository and \$GNULIB_REVISION is set, then that revision is checked
9109939400SAndreas Gruenbacher   out.
9209939400SAndreas Gruenbacher
9309939400SAndreas Gruenbacher * Otherwise, if this package is in a git repository with a 'gnulib'
9409939400SAndreas Gruenbacher   submodule configured, then that submodule is initialized and updated and
9509939400SAndreas Gruenbacher   sources are fetched from there.
9609939400SAndreas Gruenbacher
9709939400SAndreas Gruenbacher * Otherwise, if the 'gnulib' directory does not exist, Gnulib sources are
9809939400SAndreas Gruenbacher   cloned into that directory using git from \$GNULIB_URL, defaulting to
9909939400SAndreas Gruenbacher   $default_gnulib_url.
10009939400SAndreas Gruenbacher   If \$GNULIB_REVISION is set, then that revision is checked out.
10109939400SAndreas Gruenbacher
10209939400SAndreas Gruenbacher * Otherwise, the existing Gnulib sources in the 'gnulib' directory are
10309939400SAndreas Gruenbacher   used.  If it is a git repository and \$GNULIB_REVISION is set, then that
10409939400SAndreas Gruenbacher   revision is checked out.
10509939400SAndreas Gruenbacher
10609939400SAndreas GruenbacherIf you maintain a package and want to pin a particular revision of the
10709939400SAndreas GruenbacherGnulib sources that has been tested with your package, then there are two
10809939400SAndreas Gruenbacherpossible approaches: either configure a 'gnulib' submodule with the
10909939400SAndreas Gruenbacherappropriate revision, or set \$GNULIB_REVISION (and if necessary
11009939400SAndreas Gruenbacher\$GNULIB_URL) in $me.conf.
11109939400SAndreas Gruenbacher
1127fa8417cSAndreas GruenbacherRunning without arguments will suffice in most cases.
