# Slackware build script for cc65

# 20170703 bkw:
# - Update for 2.16_20170630. Upstream still hasn't done a release, but
#   again there's lots of development.
# - My self-hosted source tarball now includes the HTML documentation. This
#   script used to build it, but -current's linuxdoc-tools chokes on it,
#   and fixing it would require me a week or two probably. So, for now
#   anyway, the tarball includes docs that were built on 14.2.

# 20170129 bkw:
# - Update for v2.15_20170126, aka git 6878ede. Upstream hasn't done
#   a release since 2013 or so, but there's been lots of development.
#   Script modified enough that it can no longer build v2.13.3; use
#   the one from SBo's 14.1 repo if you need the old version for some
#   reason. Source is created from a git checkout, see git2targz.sh.
