Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that 'gmic' could not be built reproducibly.
The attached patch strips the build date from help messages. Once
applied, gmic can be built reproducibly in our current experimental
framework.
Regards,
Alexis Bienvenüe.
