+Usage: $me [OPTION]...
Bootstrap this package from the checked-out sources.
Options:
- --gnulib-srcdir=DIRNAME Specify the local directory where gnulib
- sources reside. Use this if you already
- have gnulib sources on your machine, and
- do not want to waste your bandwidth downloading
- them again.
- --copy Copy files instead of creating symbolic links.
- --force Attempt to bootstrap even if the sources seem
- not to have been checked out.
- --skip-po Do not download po files.
- --cvs-user=USERNAME Set the username to use when checking out
- sources from the gnulib repository.
-
-If the file bootstrap.conf exists in the current working directory, its
+ --gnulib-srcdir=DIRNAME specify the local directory where gnulib
+ sources reside. Use this if you already
+ have gnulib sources on your machine, and
+ do not want to waste your bandwidth downloading
+ 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
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.
