description="
GNU parser generator.

Bison is a general-purpose parser generator that converts an annotated
context-free grammar into a deterministic LR or generalized LR (GLR)
parser employing LALR(1) parser tables.  As an experimental feature,
bison can also generate IELR(1) or canonical LR(1) parser tables.
Once you are proficient with Bison, you can use it to develop a wide
range of language parsers, from those used in simple desk calculators
to complex programming languages.
