> I don't even know what pgen is or why I'd want to build it...
pgen is the parser generator, taking Grammar/Grammar as input and generating Include/graminit.h and Python/graminit.c. Only useful when you're changing Python's grammar, but without the ability to build pgen, it's hard for Windows developers to play with the grammar at all.

_freeze_importlib was what I used for a guide initially, and will be again when I get around to redoing the patch :) |
