# This script populates the build infrastructure in the source tree

#
# This script requires:
#   - Autoconf
#   - Automake
#   - Wget
#   - Git
#   - XZ Utils
#
# By default, it fetches Gnulib as a git submodule.  If you already
# have a local copy of Gnulib, you can avoid extra network traffic by
# setting the GNULIB_SRCDIR environment variable pointing to the path.
#
# In addition, it fetches the archive.dir.tar.gz file, which contains
# data files used by the autopoint program.  If you already have the
# file, place it under gettext-tools/misc, before running this script.
#
# Usage: ./autogen.sh [--skip-gnulib]
#
# Usage after a git clone:              ./autogen.sh
# Usage from a released tarball:        ./autogen.sh --skip-gnulib
# This does not use a gnulib checkout.
