difference between export and bundle

[McClain Looney]

Hello,

As a new user of mercurial (though a long-time user of cvs &  svn), I'm
unclear as to when to use export, and when to use bundle.

>From what I can tell, bundle will include binary deltas, and is made in
comparison to an accessible archive, whereas export will only export text
deltas, and can be generated as the delta from 2 local revs.

If I'm correct about the function of these commands, which would be
appropriate to move changes between 2 local and one remote repo, where
local repo A doesn't have push access to remote repo R (but R is
http-exported), and local repo B (think work/home) does have ssh push
available.

What I'm currently doing is running a bundle from A, mailing it to B, who
then unbundles and ssh-push's to R.

I'd really like to be able to make a bundle from local revisions, to
obviate the need for R being http-available. Are there plans for this? or
an extension?

Thanks,

-mml
