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.

If the file bootstrap.conf exists in the current working directory, its
contents are read as shell variables to configure the bootstrap.

Running without arguments will suffice in most cases.
