# Slackware build script for gnulib

# Written by B. Watson (urchlay@slackware.uk)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# Heavily based on Debian's package:
# https://packages.debian.org/sid/gnulib

# According to the gnulib docs at http://www.gnu.org/software/gnulib/,
# this build shouldn't exist: "there is no distribution tarball;
# the idea is to copy files from Gnulib into your own source tree."
# However, Debian packages it, and some projects that use it expect it
# to be installed system-wide (notably, lbzip2 does this). For practical
# reasons, I'm going to package this. Hopefully this saves someone else
# some work in the future.

# 20230214 bkw: BUILD=2, make this noarch, no other changes.
