# Slackware build script for xa

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

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

# 20201024 bkw:
# - update for xa-2.3.11 (dxa still the same)
# - add support for running the test suite
# - exclude windows (visual studio) stuff when extracting tarball

# 20191129 bkw:
# - update for xa-2.3.10 and dxa-0.1.4
# - remove the patches for dxa, 0.1.4 has all the fixes applied
# - switch to naptime URLs since upstream breaks download links
#   every time a new release comes out

# 20170711 bkw:
# - update for xa-2.3.8
# - REALLY remove unused *.txt.1 copies of the patches (wtf?)

# 20150322 bkw:
# - update for xa-2.3.7
# - remove unused *.txt.1 copies of the patches

# 20141030 bkw: take the tiny little patches out of DOWNLOAD= since
# they were included in the script tarball all along.
