# This script populates the build infrastructure in the source tree
# checked-out from VCS.
#
# This script requires:
#   - Autoconf
#   - Automake >= 1.13
#   - Wget
#   - XZ Utils
# If not used from a released tarball, it also requires either
#   - the GNULIB_SRCDIR environment variable pointing to a gnulib checkout, or
#   - a preceding invocation of './gitsub.sh pull'.
#
# 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]
