# Slackware build script for gzdoom

# Written by B. Watson (yalhcru@gmail.com)

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

# 20170610 bkw:
# - Renamed to gzdoom-legacy. Too much effort to keep testing old
#   gzdoom versions every time there's a new release, so the regular
#   gzdoom build will only support the newest version. If you're
#   wondering why I keep supporting old versions, it's because I have
#   old hardware. Doom is from the 1990s, it shouldn't need a $5000
#   gaming rig to play properly in 2017.

# 20170324 bkw:
# - Updated for 2.4.0.

# 20170207 bkw:
# - BUILD=2
# - Get rid of private fmodapi, now that the SBo fmodapi has been updated
#   to a new enough version. Re-add fmodapi to REQUIRES.
# - Fix download link so we always get the correct filename.

# 20170113 bkw:
# - Updated for 2.3.2. 1.9.1 and 1.8.09 still work, too.
# - Use newer version of fmodapi. Due to licensing confusion, the
#   fmodapi version on SBo hasn't been upgraded in forever. So this
#   build now uses its own dedicated fmodapi, which installs to
#   a private directory (won't conflict with system fmodapi, if present).

# gzdoom in windowed mode wants to display its git tag and hash as part

# date is the build date.
