Hi, help2man got me again.
I wasted 20 minutes debugging help2man because it outputs
a completely unhelpful message:
help2man: can't get `--help' info from inspect
when the program writes to stderr.
David Bremner suggested to at least documenting this design
choice. Please consider the enclosed patch.
Thanks,
-Steve
