# Slackware build script for inform

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

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

# 20210831 bkw:
# - updated for v6.35_r2 (upstream changed their version numbering
#   scheme again). script had to change a lot, so can't build old
#   versions any more.

# 20201104 bkw: updated for 6.34_6.12.4. In case anyone's wondering
# why I use a self-hosted URL for the source, it's because upstream
# moves the old source immediately when a new release is made. Also
# moved the binary to /usr/games and the man page to section 6.

# 20191216 bkw: updated for 6.34_6.12.2. The secondary version number
# is the inform6 library version. This script can no longer build the
# old 6.32.1 version, but it should be fine for future releases.

# The old 6.32.1 release shipped with a lot more include
# files. Upstream removed a lot of them because they were either buggy
# or license-incompatible. If you're trying to compile something that
# needs any of these old includes, please let me know. If there's enough
# demand, I'll dig up the old includes and re-add them to the package.

# Makefile can create a few symlinks to support this, but let's
# be more all-inclusive. We got 8 .h files, and end up with 70+
