# maintained in your version control; gnulib comes with a template
# build-aux/bootstrap.conf to get you started.

Usage: $me [OPTION]...
Bootstrap this package from the checked-out sources.
Optional environment variables:
GNULIB_SRCDIR Specifies the local directory where gnulib
sources reside. Use this if you already
have gnulib sources on your machine, and
you want to use these sources.
GNULIB_REFDIR Specifies the local directory where a gnulib
repository (with a .git subdirectory) resides.
Use this if you already have gnulib sources
and history on your machine, and do not want
to waste your bandwidth downloading them again.
Only used for phase 1 (--pull).
GNULIB_URL URL of the gnulib repository. The default is
$default_gnulib_url,
which is Gnulib's upstream repository.
Only used for phase 1 (--pull).
Options:
--pull Do phase 1: Pull files from the network.
--gen Do phase 2: Generate files from local files
(no network access).
(The default is to do both phases.)
--gnulib-srcdir=DIRNAME Specifies the local directory where gnulib
sources reside. Use this if you already
have gnulib sources on your machine, and
you want to use these sources. Defaults
to \$GNULIB_SRCDIR.
--gnulib-refdir=DIRNAME Specifies the local directory where a gnulib
repository (with a .git subdirectory) resides.
Use this if you already have gnulib sources
and history on your machine, and do not want
to waste your bandwidth downloading them again.
Defaults to \$GNULIB_REFDIR.
Only used for phase 1 (--pull).
--bootstrap-sync If this bootstrap script is not identical to
the version in the local gnulib sources,
update this script, and then restart it with
/bin/sh or the shell \$CONFIG_SHELL.
--no-bootstrap-sync Do not check whether bootstrap is out of sync.
--copy Copy files instead of creating symbolic links.
Only used for phase 2 (--gen).
--force Attempt to bootstrap even if the sources seem
not to have been checked out.
--no-git Do not use git to update gnulib. Requires that
\$GNULIB_SRCDIR or the --gnulib-srcdir option
points to a gnulib repository with the correct
revision.
Only used for phase 1 (--pull).
--skip-po Do not download *.po files.
Only used for phase 1 (--pull).

cat <<EOF
If the file bootstrap.conf exists in the same directory as this script, its
contents are read as shell variables to configure the bootstrap.
For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
are honored.
Gnulib sources can be fetched in various ways:
* If GNULIB_SRCDIR is set (either as an environment variable or via the
--gnulib-srcdir option), then sources are fetched from that local
directory. If it is a git repository and the configuration variable
GNULIB_REVISION is set in bootstrap.conf, then that revision is
checked out.
* Otherwise, if this package is in a git repository with a 'gnulib'
submodule configured, then that submodule is initialized and updated
and sources are fetched from there. If GNULIB_REFDIR is set (either
as an environment variable or via the --gnulib-refdir option) and is
a git repository, then it is used as a reference.
* Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
are cloned into that directory using git from \$GNULIB_URL, defaulting
to $default_gnulib_url; if GNULIB_REFDIR is set and is a git repository
its contents may be used to accelerate the process.
If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
then that revision is checked out.
* Otherwise, the existing Gnulib sources in the 'gnulib' directory are
used. If it is a git repository and the configuration variable
GNULIB_REVISION is set in bootstrap.conf, then that revision is
checked out.
If you maintain a package and want to pin a particular revision of the
Gnulib sources that has been tested with your package, then there are
two possible approaches: either configure a 'gnulib' submodule with the
appropriate revision, or set GNULIB_REVISION (and if necessary
GNULIB_URL) in bootstrap.conf.
Running without arguments will suffice in most cases.
