Module Getopt::Long 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 `--'.
