have been left largely untouched due to use of Bash-exclusive
functions and variables such as $BASH_SOURCE, pushd and popd.
Quake now will build and run on Serenity. There are a few issues,
that'll stop you from playing currently, however, such as SDL
not having any keyboard input, as well as `printf_internal` throwing
an assertion over the `.` format specifier. However, the game launches
perfectly.
