[p4] Drawing branch-diagrams

[Felix Drueke]

Hi,

we have a whole jungle branches for the development of new
features of our various software-products.
Each of these branches has a purpose and a planned end-date (which often changes)
and has a designated target-branch (usually a so-called main-line) to that its
changes will be integrated.

In order to bring a bit light into the jungle I started to draw diagrams
which show what branches exist, what integrations have to be performed (from where to
where) and what the planned end-dates for each branch are.
I'm doing that with MS-Visio which hurts, because I spent more and more time
updating the diagrams and drawing new lines (for branches or integrations between the branches).

Does anyone do something similar? What tool(s) can you recommend?

Thanks for any hints,
Felix
