Set up efl-modified git-phab from https://git.enlightenment.org/devs/zmike/git-phab.git/ (more info here https://github.com/freedesktop/git-phab)
Do something like git phab attach -r <reviewer,names,go,here> -p efl,<other,project,names> in a branch where the only commits in the branch that are past master are the ones you want uploaded
Read git-phab script for cmdline options
Ideally I'd like to make "more correct" modifications so that we can upstream these changes (the maintainer of git-phab said he would be fine with merging any patches) and not all be running some pastebin script...
