# PhysicsFS; a portable, flexible file i/o abstraction.
#
# Please see the file LICENSE.txt in the source's root directory.

# The CMake project file is meant to get this compiling on all sorts of
#  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.
