PHYSFS_setSaneConfig() isn't required.
Also, there's nothing in PHYSFS_setSaneConfig() that can't be done
outside of the library (although an internal case-insensitive string
compare snuck in there, you can replace it with stricmp/strcasecmp)...it
deliberately only uses external API calls, and really should have been a
piece of example code in the "extras" directory instead of an API
function itself...feel free to cut-and-paste the source to
PHYSFS_setSaneConfig() into your application and use just the pieces
that you need.
In your case, you probably want to set the write dir to some upper-level
directory, call PHYSFS_mkdir() to make the actual write directory you
want inside that upper-level directory, then call PHYSFS_setWriteDir()
again with the correct location. This is what PHYSFS_setSaneConfig does.
