a BtYacc patch page
Here are patches for btyacc (a backtracking derivative of the
old Berkeley parser-generator Yacc).
The btyacc home page is Siber Systems BtYacc: BackTracking Yacc.
Recent work has been done by Richard Atterer as part of his Debian btyacc package.
As of July 2001, one can find a recent version of btyacc by first checking Siber Systems BtYacc for the current release, and then checking the Debian btyacc package for the current Debian patch.
I welcome further patches, comments, etc - email@example.com. Various additional work might be done. Adding a ./configure;make installation aid, for instance. This is much more likely to happen if folks tell me they are actually using btyacc. :)
