Hello Sylvain,
having additional start scripts is not nice IMO. Therefore I removed some time ago the bin/runclient.bat and .sh for the instrumentation client (http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/tools/instrumentation/bin/Attic/) and added a target "start-instrumentation-client" into a build file named "instrumentation-build.xml" (http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/tools/targets/instrumentation-build.xml). This makes the startup independent on the OS. You only have to type "build start-instrumentation-client" in Cocoon root (this makes even changing the directory unnecessary :) ).
I would like to see this file removed again.
No problem. As I wasn't aware of this, I added a readme.txt in the tools/instrumentation directory to instruct users of this super-secret build target.
Thanks. The OS-independency is it worth :) I also had a look for documentation on the instrumentation client - there is absolutely none, no official, no wiki, no nothing.
