Bootstrap this package from the checked-out sources.
Options:
2011-03-21 06:53:52 -04:00
--gnulib-srcdir=DIRNAME specify the local directory where gnulib
2010-05-06 16:51:08 -04:00
sources reside. Use this if you already
have gnulib sources on your machine, and
do not want to waste your bandwidth downloading
2011-03-21 06:53:52 -04:00
them again. Defaults to \$GNULIB_SRCDIR
--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
--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 point to a correct gnulib snapshot
--skip-po do not download po files
If the file $me.conf exists in the same directory as this script, its
2010-05-06 16:51:08 -04:00
contents are read as shell variables to configure the bootstrap.
For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
are honored.
Running without arguments will suffice in most cases.
