When repoman is run with --echangelog, ECHANGELOG_USER from make.conf is used. It would be nice if when echangelog is run on its own, it sourced this variable from a file, preferably make.conf. As a non-gentoo-dev, the default behavior of ${user}@gentoo.org doesn't work for me, and so if I decided to call echangelog outside of repoman (and there are occasions where this may be the case), I'd be forced to either set it every time I go to work on my overlay, or have it poluting my list of env variables all the time. So it'd be useful to have echangelog source this variable from somewhere. Based on the fact that repoman uses it when set via make.conf, I think this makes sense as an appropriate place to check for it. Thanks in advance for your time.
we can't source any portage file directly ... the system is too flexible. it would also tie the tool to portage which it currently is not. we can't really run `portageq envvar` because portageq is way too slow what's wrong with making an alias ? alias echangelog='ECHANGELOG_USER=... echangelog' a command line option there might not be a bad idea either ... should make it smarter and when it detects something like git, try running `git var GIT_COMMITTER_IDENT`.
