re: Paul's "I'm not sure I see why you'd want to run lib2to3 with the embedded distribution anyway. Surely you'd do any 2to3 conversion in a normal development installation"

lib2to3 is a library useful for doing things with Python code.  Not just a stand alone tool.

Kirk: Could you please post your change as a pull request on https://github.com/python/cpython/ rather than attaching individual files here.  a full file isn't a reviewable change.

Also, Grammar.txt is loaded and saved as a cached pickle file for speed.  When packaging up an embedded stdlib bundle I recommend shipping that pickle.  (loaded in pgen2/grammar.py).

both probably need to use https://docs.python.org/3.6/library/pkgutil.html#pkgutil.get_data to read the file out of the package rather than assuming it lives on a filesystem.

using the zipfile module within lib2to3 to try and figure out when it should look somewhere other than a filesystem is the wrong approach.
