%description
    peg(1) and leg(1) are tools for generating recursive-descent
    parsers: programs that perform pattern matching on text. They
    processes a Parsing Expression Grammar (PEG) to produce a program
    that recognises legal sentences of that grammar. peg(1) processes
    PEGs written using the original syntax described by Ford while
    leg(1) processes PEGs written using slightly different syntax and
    conventions that are intended to make it an attractive replacement
    for parsers built with lex(1) and yacc(1). Unlike lex(1) and
    yacc(1), peg(1) and leg(1) support unlimited backtracking, provide
    ordered choice as a means for disambiguation, and can combine
    scanning (lexical analysis) and parsing (syntactic analysis) into a
    single activity.
