Perl module for extended processing of command line options
Module GetoptLong implements an extended getopt function called GetOptions. This function implements the POSIX standard for command line options, with GNU extensions, while still capable of handling the traditional one-letter options.
In general, this means that command line options can have long names instead of single letters, and are introduced with a double dash `–’.
Optionally, GetoptLong can support the traditional bundling of single-letter command line options.
