All this accomplishes is to make bison depend on flex, which in turn depends on bison. (So as a result, during the stdenv bootstrap, bison gets built 6 (!) times.)

longDescription = ''
|
|
Bison is a general-purpose parser generator that converts an
|
|
annotated context-free grammar into an LALR(1) or GLR parser for
|
|
that grammar. 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.
|
|
|
|
Bison is upward compatible with Yacc: all properly-written Yacc
|
|
grammars ought to work with Bison with no change. Anyone
|
|
familiar with Yacc should be able to use Bison with little
|
|
trouble. You need to be fluent in C or C++ programming in order
|
|
to use Bison.
