+ (description "peg and leg are tools for generating recursive-descent
+parsers: programs that perform pattern matching on text. They processes a
+Parsing Expression Grammar (PEG) [Ford 2004] to produce a program that
+recognises legal sentences of that grammar. peg processes PEGs written using
+the original syntax described by Ford; leg processes PEGs written using
+slightly different syntax and conventions that are intended to make it an
+attractive replacement for parsers built with lex and yacc. Unlike lex and
+yacc, peg and leg 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.")
