Dear Maintainers,
I simply don't know, how to call the function
menu with a 2D string array as second argument,
so I wrote my own one.
Best regards,
Stefan Pofahl

## @deftypefn {Function File} {} menu (@var{title}, @var{opt1}, @dots{})
## Print a title string followed by a series of options. Each option will
## be printed along with a number. The return value is the number of the
## option selected by the user. This function is useful for interactive
## programs. There is no limit to the number of options that may be passed
## in, but it may be confusing to present more than will fit easily on one
## screen.
