diagram of branches

[wiggers]

Hi,
I'm wondering if anyone knows of any way I can get a diagrammatic view
of branches within a CVS project. In our project, we sometimes get
multiple branches, and it's easy to forget from which version a
particular branch was taken. It'd just be nice to see a picture of all
branches in a project - all tagged versions within each branch, and
where branches got merged back into the head. I use CVS within Eclipse,
so perhaps there is a plug-in? Below is an exaple of what I'd like to
see:

                          HEAD
           my_branch_1_1    |    my_branch_1_2
           .--------------v1_0----------------.
           |                |                 |- v1_2_1
           |- v1_1_1        |                 |
           |                |                 |
           \------------> v1_1                |
               merge        |                 |
                          v1_2<---------------/
                            |      merge
                            |

Many thanks,
Wiggers
