# Slackware build script for hatari

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

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

# 20180612 bkw:
# - updated for v2.1.0.

# 20170307 bkw:
# - BUILD=2
# - add missing mkdir -p $TMP $PKG $OUTPUT (wtf did I do?!)
# - binaries in /usr/games, not /usr/bin.
# - man pages in section 6, not 1.
# - install missing doc/fr/clavier-exemple.txt.
# - previously SDL2 was optional and undocumented, add SDL2=no option
#   and document in README.
# - stop spamming icon symlinks to /usr (they belong in $PKG/usr of course)
# - update mime and desktop stuff. upstream started including a mime XML
#   package, but it's missing some of the stuff from my hatari.xml. The
#   new hatari.xml incorporates upstream's new stuff.

# 20170122 bkw:
# - updated for v2.0.0.

# 20160730 bkw:
# - updated for v1.9.0.
# - install some missing docs, including the French man page.
# - get rid of empty & useless /etc/hatari/ in package. strace
#   shows that hatari never even looks there for a conf file,
#   it looks for /etc/hatari.cfg (which we don't ship).

# 20141029 bkw: add missing : in VERSION BUILD TAG assignments

# 20140825 bkw:
# - updated for v1.8.0
# - install docs/manpages to right places, instead of moving after the fact
# - get rid of the need for a symlink /usr/doc/hatari
# - only symlink emutos.img -> tos.img if no link already exists, so
#   reinstalling the package won't reset the default ROM.
# - add mime type and auto-associate ST disk images and executables.
