# If you don't specify pcsx2, plugins, or a plugin name, it will assume you want to rebuild everything.
# If you don't specify dev or debug, it assumes a release build.
# If it isn't all, install, or clean, it assumes install.

# If you want other options, add them to $pcsx2_build_types. This is still a work in progress...
