Hi Jeroen,

If the tools are to build files of a particular type (say .vrb files), you can 
do it in the actions section. But then the check to build the tool will be 
before every compilation call.

Otherwise you're hitting the same problem I have which is that there is no (to 
my mind) easy way to specify this kind of dependency at the moment. Maybe the 
build-project rule will do it but it is sort of against the demand-driven 
philosophy.

Best Regards,
Matt
