yacc

Customized version of ply.yacc parser

This is a modified version of ply.yacc (from PLY 3.11) that removes support for loading parse tables from picklefiles or arbitrary locations on the filesystem. yacc() is expected to be used in a “2-pass” mode: either called to generate the parse table module, or else passed the imported parse table module to return a fully-constructed parser.

The YACC logic itself is unchanged from the original distribution.
