20  Contains cross platform classes and utilities for starting, stopping and monitoring processes.  
21   
22  The module contains the base class L{pysys.process.user} that can be extended by subclasses that  
23  require the ability to start, stop, interact and monitor processes started by the PySys  
24  framework. Subclasses within the framework are the L{pysys.basetest.BaseTest} and  
25  L{pysys.baserunner.BaseRunner} classes, both of which may be required to start processes as part  
26  of the execution of a set of testcases. The import path of the helper and monitor modules is set up 
27  at runtime so as to select either the Win32 modules (located in pysys.process.plat-win32), or the  
28  unix modules (located in pysys.process.plat-unix); both modules are written to display common  
29  functionality in order to provide a unified abstraction where the user is not required to select the  
30  correct modules based on their current operation system.
