Hi!

Well, I think it is more likely that the user wants to refer to an existing
target rather than refering to a future target.
Likewise verify complains about a missing manual page (Documentation) and
about missing executables.

Command ... is not executable: No such file or directory
...: man ... command failed with code 16

To be consistent, verify should also complain about missing targets referred
to.
(The manual page and executable could be added at some later time, too)

Ulrich
