+ -grmlhome store hidden files from \$HOME (\$HOME/.*) of user grml [use as user root]
+ -etc store modified files from /etc
+ -configdir store \$HOME/config
+ -all store all configuration files (:= -home, -configdir and -etc)
+
+ Notice: it is also possible to use environment variables:
+ \$SAVE_HOME, \$SAVE_GRMLHOME, \$SAVE_ETC, \$SAVE_CONFIGDIR and \$SAVE_ALL
