-/*
- * getopt - get option letter from argv
- *
- * This is a version of the public domain getopt() implementation by
- * Henry Spencer, changed for 4.3BSD compatibility (in addition to System V).
- * It allows rescanning of an option list by setting optind to 0 before
- * calling, which is why we use it even if the system has its own (in fact,
- * this one has a unique name so as not to conflict with the system's).
- * Thanks to Dennis Ferguson for the appropriate modifications.
- *
- * This file is in the Public Domain.
