class documentation

class Process(object):

Known subclasses: niryo_libraries.roslaunch.pmon.DeadProcess

Constructor: Process(package, name, args, env, ...)

Basic process representation for L{ProcessMonitor}. Must be subclassed to provide actual start()/stop() implementations.

Constructor must be called from the Python Main thread in order for signal handlers to register properly.
