Re: [Monotone-devel] How to split a project

[J Decker]

The other method is to make a quick commit with --branch=program1
branch pivot_root  < program1's new root directory> old_root - will
put all files in the root into old_root and make the program
directories current.  You can then use mtn drop to drop old_root.

this is bad, in that you cannot propagate to this new changes to the
common trunk... but if you're really just making a new trunk, but want
to retain the revision history, as long as you do not ever propagate
between these, it's not so bad.

Oh I guess the more important direction is that you cannot propagate
from the pivoted branch to the main, as it would inherit the pivot.  I
really this the pivot point should be handled differently....

maybe someone could make a new operation that is a sensible 'make this
point in a branch a seperate branch, which I can propagate to and from
the main trunk (only changes to files within that branch basically)'
