18 Notes:
19 1) If "command usage line" contains white space, it must be given as a
20    quoted string.
21 2) "command usage line" may contain both literal fields and variable
22    fields.  These fields are distinguished in the output by presenting
23    the variable fields in 10pt Helvetica Bold Italic instead of Roman.
24    Variable fields are denoted by enclosing them between tilde (~)
25    characters.  For example
26 
27       "command ~args~ {-~control_args~}"
28 
29    will present "command" in Roman and "arg" and "control_args" in Bold
30    Italic.
