Newbie experience with push over ssh

Hi,

I'm playing a bit with git (still ~ total beginner).

I could create a local repository, commit in it, but then, I tried to push it to a remote machine, on which git is installed.

I would have expected "push" to do this, but:

$ git push ssh://machine.fr/tmp/foo fatal: '/tmp/foo': unable to chdir or not a git archive fatal: The remote end hung up unexpectedly

Then, I tried "clone":

$ git clone . ssh://machine.fr/tmp/foo
Initialized empty Git repository in /tmp/foo/ssh:/machine.fr/tmp/foo/.git/
remote: Generating pack...
remote: Done counting 3 objects.
remote: Deltifying 3 objects.
 100% (3/3) done/3) done
remote: Total 3 (delta 0), reused 0 (delta 0)
Indexing 3 objects.
 100% (3/3) done

Gosh, "push" seems to know what a URL is, but not "clone", which considers the _file_ ssh:/machine.fr/tmp/foo ...

Then only, I understood that I would have to log onto the remote machine, and mkdir + git init manually. At least, this should be mentionned in the git-push man page, but indeed, is there any reason why git-push could not just create the remote repository? And any reason why clone doesn't deal with URLs?

Thanks,
