#260 finding dot version fails

[Pearu Peterson]

$ dot -V
dot - Graphviz version 2.12 (Tue Sep 4 17:03:38 UTC 2007)

but epydoc seems to use

r'dot version ([\d\.]+)'

pattern for version matching.

I've the same problem under Windows:

>dot -V
dot - Graphviz version 2.17.20080228.0540 (Thu Feb 28 08:55:09 GMT 2008)

but epydoc tell:

Info: Detected dot version 0

and the graph is corrupted (just a small square).

thx,

Manuel
