hi Junio,

it should merge the changes as if I'd run git-pull on the remote box,
and handle conflicts in the same way.

If possible I want to get exactly the effect of having run on box B
"git-pull A", by running a command like "git-push B" on box A.  I think
maybe that's not possible without commiting all changes to the working
copy on B first, but for our app it's fine to do that it's meant to do
that automatically and frequently anyway.
so I will just do that then run checkout -f from the hook.

I don't understand git very well yet but that will work I think.  I
thought "push" would be symmetrical to "pull" more or less, maybe it is
symmetrical to "fetch" ?

thank-you for your help, I am reading some more of the git manual
because I understand only some of your reply and very little about git
yet!

The app "arcs" we are writing, it is peer to peer, not necessarily using
a central repository, it commits pulls and pushes all changes made to
working copies automatically or when asked to.  currently I'm
implementing push as a remote pull because of this problem, but that
can't connect back through firewalls and suchlike.
