// Notes on deamon operation (Unix) and service operation (Win 32):

// To run pegasus as a daemon on Unix platforms, use the -d option:

// To run pegasus as a daemon on Unix platforms:

// cimserver -d

// cimserver

// The -d option has no effect on windows operation.

// To NOT run pegasus as a daemon on Unix platforms, set the daemon config

// property to false:

// cimserver daemon=false

// The daemon config property has no effect on windows operation.

// To shutdown pegasus, use the -s option:

// cimserver -s [-f] [-T timeout_value]

// cimserver -s

// To run pegasus as an NT service, there are FOUR different possibilities:
