+Usage:\n\n
+
+1.) a single parameter with NO leading -.\n
+\t  This will will then be used as the addition for our configfile. Ie. \`$0 security\` will\n
+\t  have us look for ${NAME}-security.{conf,mirror} files.\n\n
+
+2.) using getopt style parameters:\n
+\t -a [NAME]   - Same as 1.) above, used for the config files. Default empty.\n
+\t -k [TYPE]   - Type of push. all, mhop. Default all.\n
+\t -s [STAGE]  - Stage of push. stage1, stage2, all. Default all.\n
+\t -f          - Run from within the mirrorscript ftpsync. Don't use from commandline!\n
+\t -h          - Print this help and exit
