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.

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 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.
