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.
|

--copy copy files instead of creating symbolic links

--force attempt to bootstrap even if the sources seem

not to have been checked out

If the file bootstrap.conf exists in the same directory as this script, its

For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR

are honored.

Gnulib sources are assumed to be present:

* in \$GNULIB_SRCDIR, if that environment variable is set,

* otherwise, in the 'gnulib' submodule, if such a submodule is configured,
