/*
 * san_test.c: A small app to test the functionality of san, my
 *    Swiss Army Nife tool-lib and to show how to use it.
 *    Actually only focused on cmdla which parses commandline

 * 01/14/2006: Georg Steffers - First implemented
 * 01/15/2006: Georg Steffers - V0.1 ready. Modified much and many
 *                              now long arguments are supported as
 *                              well as arguments with am optional
 *                              parameter.
 * 01/23/2006: Georg Steffers - add support for gettext.
 * 01/24/2006: Georg Steffers - renamed to san_test.c as it should reflect
 *                              the whole lib as it grows.
