PGP::Sign 0.19

I added Debian packaging rules and uploaded a new version of PGP::Sign, and then one of the excellent CPAN testers pointed out that the GnuPG support didn't work with non-C locales. I hadn't realized I'd not converted the GnuPG code to use --status-fd, so I did that and released this version.

You can get the latest version from either CPAN or the PGP::Sign distribution page.
