Marcu's annotation tool!

[Naila Mimouni]

Hi,
I am trying to play with Marcu's annotation tool and I am having some problems.
I downloaded the linux version along with the appropriate graphviz software it
needs.

when I loaded the text into the text window and tried to identify the
boundaries (left mouse button as indicated in the manual) nothing appeared on
the RST window or the text window.

Does this have anything to do with the version of wish I am using (wish 2.8)
and if it does then which version are we supposed to use???

Or is it dot???? In my RSTTool and RSTTool.tcl files I have:

if {$DOT_EXISTS == "YES"} {
    set DOT     "~nkm23/software/RST/gv1.7c/bin/dot"
could this be the problem????

Help.

Thanks.

Naila
