Note to self: what is the direction of a git rebase?

tl;dr

git checkout BRANCH-TO-REBASE
git rebase ON-TOP-OF [BRANCH-TO-REBASE]

Is what I almost always use. If it was for this usage only, there should just be a command named git rebase-on to clear all confusion.

Sure, I have read the manpage. Now I’m sorry to say, the meaning of the git rebase arguments is quite abstruse:

I removed irrelevant options:

       git rebase [--onto <newbase>]
               [<upstream> [<branch>]]

In particular, the existence of the --onto option has always confused me, because I thought that calling git rebase master precisely meant “rebase on master”.

Anyway, thank you git for providing us with commands so versatile that each time I need to rebase I spend 15 minutes trying to understand again the manpage.
