I know. There is also Source-Navigator from Cygnus/RedHat
(http://sources.redhat.com/sourcenav/). I haven't played with cscopy
(only looked at it some time ago), I did play some with SourceNavigator.
I just think that SourceInsight people got this thing right. I almost
enjoy using it (which is quite a feat since I'm mostly frustrated that
software doesn't do what I would like it to do the way I think it should
be done).
