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

# 20210809 bkw: update for v3.5, many changes, can't build old versions.
# - Relicense as WTFPL, with permission from the original author.
# - Build & install the actual HTML docs (not the bundled copy of
#   the upstream website).
# - Don't install fonts. They were part of the above.
# - Use upstream's .desktop files instead of our own.
# - Upstream removed the man pages; restore them (for now).
# - Build the gtk+3 UI. Also build the SDL2 UI, unless the user's
#   requested the SDL1 one (or disabled SDL).
# - Really fix the paths in the documentation.
# - ffmpeg now included in Slackware (pre-15.0 -current). Still
#   autodetected, but the docs no longer mention it.
# - Get rid of README_SBo.txt as the build options are simpler
#   and "fit" in the regular README now.

# 20200801 bkw:
# - Take over maintenance
# - Autodetect ffmpeg
# - Allow building with SDL 1.x
# - Allow building without pulseaudio
# - Get rid of xa dep
# - Install TTF fonts in correct place, get rid of other formats
# - install-info in doinst.sh so vice.info shows up in the info dir
# - Have slack-desc show build options
# - Re-enable the old x64 emulator
# - BUILD=3
