+5. Start it up - see usage below
+
+Usage
+=====
+ - `$ menu -c menufile` (display the menufile using simple curses based menu)
+ - `$ menu -n menufile` (display the menufile using newt character graphics menu)
+ - NOTE: In the menufile you can call menus of other types (e.g. a newt menu can call a curses menu) but you have to hard code that into the menufile - example in the repo (menufile calls menufile2 as a curses menu).
 
 menufile - format
 =================
- - Max length of each line - 80 chars.
+ - NOTE: IF you exceed these lenghts it will mess your menu's up
+ - Max lengh of description line is 30 chars
+ - Max length of each command line - 80 chars.
    - NOTE: If you're in any doubt about the length of the command, wrap it up in a script (you wouldn't want your 'rm' command to land on the 80 char boundary :).
  - Max number of options - 30.
 
@@ -44,6 +53,7 @@ As time permits - here's the plan:
  - General code improvements
    - [x] Changed kerbpass to passwd
    - [x] Fixed a bug where after an execution the menu would redraw and leave the last menu option number selected displayed at the bottom of the screen - there was an redundant printw() - echo() had already been set.
+   - [ ] Handle the lines longer than 30 or 80 chars so it doesn't mess up the menu
