SystemType() {
     #
     # NAME
     #    SystemType - return the type of the system
     #
     # SYNOPSIS
     #    SystemType
     #
     # DESCRIPTION
     #    This function determines the type of the system on
     #    which it is executing and returns one of the
     #    following strings:
     #    
     #         AIX       DECOSF    HP        LINUX     SCO
     #         SGI       SOLARIS   SUNBSD    ULTRIX
     #
     #    ULTRIX is returned for Digital Equipment's older
     #    BSD systems and DECOSF is returned for their OSF
     #    based systems.
     #
     #    SUNBSD is returned for Sun BSD systems (versions
     #    4.*) and SOLARIS is returned for Sun System V
     #    systems (versions 5.*).
     #
     #    If this function is unable to determine the type
     #    of the system, it will return an empty string.
     #
