PID files
*********
The PIDFile :ref:`Engine Plugin<plugins>` is pretty straightforward: it writes
the process id to a file on start, and deletes the file on exit. You must
provide a 'pidfile' argument, preferably an absolute path::
PIDFile(cherrypy.engine, '/var/run/myapp.pid').subscribe()
.. currentmodule:: cherrypy.process.plugins
