# Slackware build script for inform

# 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.
