libparse-recdescent-perl 1.96.0+dfsg-3 (i386 binary) in ubuntu lucid

 The Perl module Parse::RecDescent, incrementally generates top-down
 recursive-descent text parsers from simple yacc-like grammar
 specifications. It provides:
 .
   * Regular expressions or literal strings as terminals (tokens),
   * Multiple (non-contiguous) productions for any rule,
   * Repeated, optional and alternate sub-rules within productions,
   * Late-bound (run-time dispatched) sub-rules
   * Full access to Perl within actions specified as part of the grammar,
   * Simple automated error reporting during parser generation and parsing,
   * The ability to commit to, uncommit to, or reject particular productions
     during a parse,
   * Incremental extension of the parsing grammar (even during a parse),
   * The ability to retrieve the generated parsing code.
