Merged Guido's mkaliases and Jack's MkPluginAliases

Mac/scripts/ConfigurePython.py

 # 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
-# but you can run it in a shared python as long as you can point
-# it to toolboxmodules.slb
 #
-# Jack Jansen, CWI, August 1995
+# This is sort-of a merger between Jack's MkPluginAliases
+# and Guido's mkaliases.
