libgetopt-tabular-perl

*Getopt::Tabular* is a Perl 5 module for table-driven argument parsing, vaguely inspired by John Ousterhout's Tk_ParseArgv. All you really need to do to use the package is set up a table describing all your command-line options, and call &GetOptions with three arguments: a reference to your option table, a reference to '@ARGV' (or something like it), and an optional third array reference (say, to '@newARGV'). &GetOptions will process all arguments in '@ARGV', and copy any leftover arguments (i.e. those that are not options or arguments to some option) to the '@newARGV' array. (If the '@newARGV' argument is not supplied, 'GetOptions' will replace '@ARGV' with the stripped-down argument list.) If there are any invalid options, 'GetOptions' will print an error message and return 0. Before I tell you all about why Getopt::Tabular is a wonderful thing, let me explain some of the terminology that will keep popping up here.
