It just says you have to install the manpages in such-and-such a place, but I don't have any. There, policy issue fixed :) More seriously, it seems to me that the only reason we have these manpages in the first place is because of emergent effects. *Maybe* I'm wrong about someone using Git.pm as an external API, is that the case? I was assuming this was more of a case where we were manifying the equivalent of Documentation/technical/api-*.txt and shipping them as user docs just because that's what EU::MM will do by default, and nobody thought to stop it. But sure, if we still want these I can just provide them, here's the relevant generated perl.mak section: POD2MAN_EXE = $(PERLRUN) "-MExtUtils::Command::MM" -e pod2man "--" POD2MAN = $(POD2MAN_EXE) manifypods : pure_all config \ Git.pm \ Git/I18N.pm \ Git/SVN/Editor.pm \ Git/SVN/Fetcher.pm \ Git/SVN/Memoize/YAML.pm \ Git/SVN/Prompt.pm \ Git/SVN/Ra.pm \ Git/SVN/Utils.pm $(NOECHO) $(POD2MAN) --section=$(MAN3EXT) --perm_rw=$(PERM_RW) -u \ Git.pm $(INST_MAN3DIR)/Git.$(MAN3EXT) \ Git/I18N.pm $(INST_MAN3DIR)/Git::I18N.$(MAN3EXT) \ Git/SVN/Editor.pm $(INST_MAN3DIR)/Git::SVN::Editor.$(MAN3EXT) \ Git/SVN/Fetcher.pm $(INST_MAN3DIR)/Git::SVN::Fetcher.$(MAN3EXT) \ Git/SVN/Memoize/YAML.pm $(INST_MAN3DIR)/Git::SVN::Memoize::YAML.$(MAN3EXT) \ Git/SVN/Prompt.pm $(INST_MAN3DIR)/Git::SVN::Prompt.$(MAN3EXT) \ Git/SVN/Ra.pm $(INST_MAN3DIR)/Git::SVN::Ra.$(MAN3EXT) \ Git/SVN/Utils.pm $(INST_MAN3DIR)/Git::SVN::Utils.$(MAN3EXT) I.e. we'd just need to create the mandir, then call pod2man. However, even then we should consider what I've noted above and decide which modules we really want to be shipping docs for, e.g. Git::I18n is never going to be used by anyone external, nor is the Git::SVN stuff. I think the only thing we're talking about shipping manpages for is *maybe* just Git.pm itself, no? I don't really care, so if others want to ship them all I'll just hack it up. This just seemed like a bug to fix while I was at it.
