I don't think we have any documentation either way. We could put
something on the wiki, but the chances are most people wouldn't find
it. Someone who wants to maintain a fork of the super-project will
need to know how to handle remotes, otherwise they'll probably just
get in a mess. Git's submodule system is fiddly enough for simple
cases. But if you want to write a page, here's the basics:

How it's done depends on the software you use. If you use the github
command line client, and clone from boostorg then fork using 'hub
fork', it will keep 'boostorg' as the 'origin' remote, and your
account's remote will be named after your username, which is what's

If not, you can clone from boostorg, then add the fork (untested):

git clone
git remote add -f danieljames
git checkout danieljames/some-branch -b some-branch

Or clone from the fork, and then add origin (also untested):

git clone -o danieljames -b some-branch
git remote add origin

If someone wants to publish a fork for others to use without doing
this, then they're going to have to mess around with the modules
anyway, I don't think it's much work to do a search and replace.
