>
> At the moment all our examples print a usage statement no matter whether the
> parameters have been provided or not. This can be confusing for people
> because an usage statement is usually only printed if one has specified a
> wrong parameter or if a parameter is missing.
> I propose to remove the unchecked printing of the usage statement.
