Usage: $me [OPTION]...
Bootstrap this package from the checked-out sources, phase 1:
Pull files from the network.
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.
GNULIB_URL URL of the gnulib repository. The default is
$default_gnulib_url,
which is Gnulib's upstream repository.
Options:
--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.
--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 points to a gnulib repository
with the correct revision.
--skip-po Do not download *.po files.
EOF

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 the environment variable GNULIB_SRCDIR is set, 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 the environment variable
GNULIB_REFDIR is set 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 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.
