How to use the py2app.build_app function in py2app

include_meta_repo = True
    sys.argv.remove('--include-meta-repo')

# This hack allows us to run custom code before/after the py2app command executes.

    __destination_libpython_dir = __dist_dir + '/ilastik.app/Contents/Resources/lib/python2.7'
    __replace_modules = ['ilastik', 'volumina', 'lazyflow']

    def run(self):
        """
        The normal py2app run() function copies the ilastik, volumina, and 
        lazyflow modules in the .app without the enclosing repo directory.
        
        This function deletes those modules from the app (after saving the drtile.so binary), 
        copies the ENTIRE repo directory for each module, and then creates a symlink to the 
        inner module directory so that the final .app doesn't know the difference.
        
        Just to be clear, our usual py2app command (including our recipes) 
        produces a lib/python2.7 directory that looks like this:

# OSX paths
SPARKLE = '/Library/Frameworks/Sparkle.framework'

# Patch py2app recipe enumerator to skip the sip recipe since it's too enthusiastic - we'll list additional Qt modules explicitly
if sys.platform=='darwin':
    from py2app import recipes
    import py2app.build_app
    def iterRecipes(module=recipes):
        for name in dir(module):
            if name.startswith('_') or name=='sip':
                continue
            check = getattr(getattr(module, name), 'check', None)
            if check is not None:
                yield (name, check)
    py2app.build_app.iterRecipes = iterRecipes


APP = 'EDMarketConnector.py'
APPCMD = 'EDMC.py'
SHORTVERSION = ''.join(VERSION.split('.')[:3])

        ...etc...            

        Hence, the ilastik, lazyflow, and volumina modules are present via symlinks,
        so the .app doesn't know the difference.
        
        Also, this function removes any dylibs in the dylib_forced_removal list from the final distribution.
