+     "PhysicsFS is a library to provide abstract access to various archives.
+It is intended for use in video games.  For security, no file writing done
+through the PhysicsFS API can leave a defined @emph{write directory}.  For
+file reading, a @emph{search path} with archives and directories is defined,
+and it becomes a single, transparent hierarchical file system.  So archive
+files can be accessed in the same way as you access files directly on a disk,
+and it makes it easy to ship a new archive that will override a previous
+archive on a per-file basis.")
