table-driven argument parsing for Perl 5

Description

Getopt::Tabular is a Perl 5 module for table-driven argument parsing, vaguely inspired by John Ousterhout's Tk_ParseArgv.

Some nice features of Getopt::Tabular are:
 * Command-line arguments are carefully type-checked, both by pattern and
   number -- e.g. if an option requires two integers, GetOptions makes sure
   that exactly two integers follow it!
 * The valid command-line arguments are specified in a data structure
   separate from the call to GetOptions; this makes it easier to have very
   long lists of options, and to parse options from multiple sources
   (e.g. the command line, an environment variable, and a configuration file).
 * Getopt::Tabular can intelligently generate help text based on your option
   descriptions.
 * The type system is extensible, and if you can define your desired argument
   type using a single Perl regular expression then it's particularly easy to
   extend.
 * Options can be abbreviated and come in any order.
 * A "spoof" mode in which arguments are parsed without side-effects.
