# xkegs refuses to close (close button greyed-out by window manager).
# Small patch by SlackBuild author fixes this large annoyance (which is
# extra-annoying because there's also no Quit option in the kegs menu).
# I've sent this upstream, maybe it'll get integrated in future versions.
patch -p1 < $CWD/allow_window_close.diff

# Matthew Miller pointed out this patch to me. Since kegs uses OSS for
# audio, and modern Slackware has ALSA OSS emulation disabled by default,
# sound won't work unless xkegs is run via aoss, or OSS modules are
# loaded. This patch allows the emulator to start with sound disabled if
# it can't open the OSS audio device (instead of it being a fatal error).
# I've also updated the README to explain how to get audio to work.

# No install target, just stick it all where it goes.
# The icon was converted from the Mac OSX icon with icns2png.
# The .desktop has 'Terminal=true' because xkegs *really* wants
# to be started from a terminal (the debugger uses stdio, and
# is too easy to accidentally enter by center-clicking the window).
