3 # SliTaz Base functions used from boot scripts to end user tools. Use
4 # gettext and not echo for messages. Keep output suitable for GTK boxes
5 # and Ncurses dialog. LibTaz should not depend on any configuration file.
6 # No bloated code here, function must be used by at least 3-4 tools. See
7 # libtaz() for a list of functions and options or run: tazdev libtaz.sh
8 # Libtaz is located in /lib/libtaz.sh since it is used when /usr may not
9 # be mounted.
