bootstrap

#!/bin/sh
# Run this after autogen.sh, to pull in all of the gnulib-related bits.
# It's important to run *after* autogen.sh, since it updates some of
# the same files autogen.sh does, yet those from gnulib are newer,
# and match the tests.  So if a gnulib bug has been fixed since the
# snapshot taken for whatever gettext release you're using, yet you
# run "make check" against the wrong version, the corresponding unit
# test in gl-tests/ may well fail.

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.

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.
