-/* pam_issue module - a simple /etc/issue parser to set PAM_USER_PROMPT
- *
- * Copyright 1999 by Ben Collins <bcollins@debian.org>
- *
- * Needs to be called before any other auth modules so we can setup the
- * user prompt before it's first used. Allows one argument option, which
- * is the full path to a file to be used for issue (uses /etc/issue as a
- * default) such as "issue=/etc/issue.telnet".
- *
- * We can also parse escapes within the the issue file (enabled by
- * default, but can be disabled with the "noesc" option). It's the exact
- * same parsing as util-linux's agetty program performs.
- *
- * Released under the GNU LGPL version 2 or later
