I am writing a game engine and I'd like it to have Python scripting as well as support for mods using PhysFS.
My game data is stored something like this:

/

native

scripts
sprites
...

mods

mymodname

scripts




What I want is for the mod scripts to be able to 'import' the native scripts as if they were in the same directory. Is something like that possible using PhysFS?
[I am the same person who asked the question.]
The solution I used eventually was to modify Python's sys.path when my program starts. This does not pollute the game's data directories with symbolic links and is overall much cleaner.
