Also, for future reference:

1. Use a single blank lines to separate thing like 'menu' and 'endmenu'.
2. Wrap your the help sensibly, don't put it all on one line.
3. It's conventional to use tabs up to below "help" and then two spaces
   to indent the help text.
4. "," always has one space after it.

Thanks.
