/* Adapted from https://github.com/skeeto/getopt by Chris Wellons */
/* A minimal POSIX getopt() implementation in ANSI C
*
* This is free and unencumbered software released into the public domain.
*
* This implementation supports the convention of resetting the option
* parser by assigning optind to 0. This resets the internal state
* appropriately.
