# This python script creates Finder aliases for all the
|
||
|
|
# dynamically-loaded modules that "live in" in a single
|
||
|
|
# shared library.
|
||
|
|
# It needs a fully functional non-dynamic python to work
|
||
|
|
# (since it creates aliases to stuff it needs itself),
|
||
|
|
# you should probably drag it onto your non-dynamic python.
|
||
|
|
#
|
||
|
|
# If you compare it to MkPluginAliases.as it also serves
|
||
|
|
# as a comparison between python and AppleScript:-)
