A useful utility function...

[Adam D. Moss]

This function can be used from an application in a similar
manner to PHYSFS_addToSearchPath(), with some useful differences:

* The string it takes is in system-independant (more specifically,
unix-like) format, including suitable munging for '..' and
successive slashes.

* The paths it adds are relative to the program's *base*
directory (as returned by PHYSFS_getBaseDir()) rather than the
user/process's current working directory.  (If you supply a path
preceded by a '/' then the path is relative to the cwd as usual
for physfs, but is still system-independant.)

This was useful for me.  Hope it's useful to someone else.
