Doing this means we no longer need to maintain our own Doom fork and
we get the newest features of the upstream repository, such as sound
effects and music.
We may need entries with spaces in makeopts, installopts, and
configopts, and at that point we should also convert depends and
auth_opts to avoid confusion.
* Use ${version} instead of explicit version numbers in urls/filenames
* Move -L option to port script, as this is always good
* Fix some various other stuff
Ports/.port_include.sh, Toolchain/BuildIt.sh, Toolchain/UseIt.sh
have been left largely untouched due to use of Bash-exclusive
functions and variables such as $BASH_SOURCE, pushd and popd.
Much redundancy is removed from package scripts with this system.
It also supports simple dependency management, uninstalling (through
BSD ports style plist files), cleaning up after itself (with clean,
clean_dist, clean_all commands), etc.
Okay, here's something we've all been waiting for. A DOOM port :^)
It's based on the "doomgeneric" port and doesn't have sound support at
the moment, but it does let you play DOOM on Serenity.
Note that you have to provide DOOM1.WAD yourself.
Fixes#33.
