Bootstrap this package from the checked-out sources.
Options:
- --gnulib-srcdir=DIRNAME Specify the local directory where gnulib
+ --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
+ 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 if
- defined.
- --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.
- --skip-po Do not download po files.
-
-If the file $0.conf exists in the same directory as this script, its
+ /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
