/**
    This abstract class has virtual methods for information that varies across
    applications. The rest of the methods are called from the application
    (i.e. cimserver.cpp), and need to be defined by every operating system
    implementation.

    This version will not touch the method names, as it is fairly risky to do
    so now.  However, the goal is to eventually standardize the interface so
    we pull out as much OS-specific function as possible from the main
    cimserver file.

    Not all operating systems need to fully implement all these methods.
    Stick methods which do not apply to your OS in a "No-ops" section at the
    top.

    See PEP#222 for more information.
