# PhysicsFS; a portable, flexible file i/o abstraction.

# Please see the file LICENSE.txt in the source's root directory.

#  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.
