Thanks I didn't think it was so simple !

I have a last question, I put my plugins in a 'twisted/plugins'
subfolder of my project, and running them from the command line works
fine. How can I invoke them in unit tests (I need to be able to start
and stop them), since the plugin files are not in a package ?
