You could look into neato or dot. I'm not quite sure what you want stuff
to look like, but it might be useful.

The syntax is easy, and you can output your diagrams in a variety of
formats.

diagraph "Org::Bgw::Pas"
{
  "something" -> "somethingelse" [dir=3Dboth len=3D2];
}

The diagram files would be small enough to check into cvs, and you
shouldnt have a hard time then generating images or whatever. From the
dot man page:

DESCRIPTION
       dot draws directed graphs.  It  works  well  on  DAGs  and
       other  graphs  that can be drawn as hierarchies.  It reads
       attributed graph files and writes drawings.   By  default,
       the  output format dot is the input file with layout coor=AD
       dinates appended.  To generate PostScript,  use  the  -Tps
       option.   Other  choices  are -Tmif (FrameMaker graphics),
       -Thpgl (HP pen plotters), and -Tpcl  (Laserjet  printers),
       -Tgif  (pixel  graphics),  -Timap,  and  -Tismap (imagemap
       files for httpd servers that mark out rectangles for  each
       node that has a non-null URL attribute.).
