+PhysicsFS is a library to provide abstract access to various archives. It is 
+intended for use in video games, and the design was somewhat inspired by Quake 3's 
+file subsystem. The programmer defines a "write directory" on the physical 
+filesystem. No file writing done through the PhysicsFS API can leave that write 
+directory, for security. For example, an embedded scripting language cannot write 
+outside of this path if it uses PhysFS for all of its I/O, which means that 
+untrusted scripts can run more safely. Symbolic links can be disabled as well, for 
+added safety. For file reading, the programmer lists directories and archives that 
+form a "search path". Once the search path is defined, it becomes a single, 
+transparent hierarchical filesystem. This makes for easy access to ZIP files in the 
+same way as you access a file directly on the disk, and it makes it easy to ship a 
+new archive that will override a previous archive on a per-file basis. Finally, 
+PhysicsFS gives you platform-abstracted means to determine if CD-ROMs are available, 
+the user's home directory, where in the real filesystem your program is running, 
+etc.
