# platforms quickly, and serve as the way Unix platforms and Linux distros
# package up official builds, but you don't _need_ to use this; we have
# built PhysicsFS to (hopefully) be able to drop into your project and
# compile, using preprocessor checks for platform-specific bits instead of
# testing in here.
