Catvet is Tomcat Configurator.
It will be written in python and gtk python.
It's purpose is being able to configure a tomcat with a few clicks instead of going and configure the xml files.
After that the configuration can be saved and reapplied again.
It will suport tomcat 6 for start (yeah I know 7 is out, but I am doing this out of need and we use tomcat 6)

Oh about the name: catvet -> Cat Vet ... Tomcat Doctor...
:P
