Paquet : btyacc (3.0+dfsg-1)

Backtracking parser generator based on byacc

btyacc is a hacked version of the original Berkeley "byacc". The main change to byacc is the addition of backtracking code, allowing you to try both alternatives in case of shift-reduce or reduce-reduce conflicts. As long as no backtracking takes place, the speed is comparable to bison's one.

Additional features:

 - Enhanced support for storing of text position information for tokens.
 - Closes the potential *yacc/bison memory leak during error recovery.
 - Preprocessor directives like %ifdef, %include.
 - C++ friendly.
