[pygame] Directories

[Kris Schnee <kschnee@xxxxxxxxxx>]

I'm trying to organize my code better. I've got modules and data files 
organized into directories like so:

Main Game Directory
  -Music, sound, etc.
  -Conch (sound code)
  -Aquablue (worldsim)
  -Driftwood (UI)
  -Pearl (Isometric display)

And here I've encountered a problem. I've been able to test each module 
on its own, and even have them automatically go up one directory to 
access the right data files when run alone by saying:

if __name__ != "__main__": ## Run when included in something else
    print "Loaded module "+MODULE_NAME+"."
else: ## Run when this program is run by itself
    print "Running module "+MODULE_NAME+", v"+VERSION
    if MODULE_NOTES:
        print MODULE_NOTES

    ## Switch to the next directory up to find data directories.
    os.chdir(os.path.split(os.getcwd())[0])

But the part I'm working on right now, the "Pearl" display, needs to 
access the Aquablue worldsim code just to be properly tested. If I put 
"import Aquablue" below the code I just gave, it can't find the module 
even though it can access the data-file directories. Will I have to 
either put Pearl in the main game directory so it can find Aquablue, or 
test it without that?
