Here's a fix suggestion, using the x-to-1 script that is in use in
GNU gettext for 5 years.
I'm not sure it's best to add that additional level of
infrastructure/indirection to Hello. E.g., it seems unnecessary to have
a skeleton when all that is being specified is the one-line description
in the [NAME] section, which can be easily done on the command line.
Meanwhile, I added the -o to the help2man invocation as Ralf suggested,
so hopefully now it won't bomb out if help2man isn't available.
Also, why not adding the help2man to build-aux?
Sounds good to me, but will Automake find it there?
I installed all your other fixes. Thank you very very much. Next
pretest coming soon ...
