#    NAME
#      diagsetup - Shell script to run diagsetup tool in
#                  standalone mode.
#
#    DESCRIPTION
#      Runs diagsetup Java application.  This file comes
#      in two forms - its original, with a .sbs extension, and its 
#      final, without a .sbs extension.  The .sbs version is 
#      source for the final version which the Oracle Universal Installer 
#      creates by doing variables substitution at install time.
#
#      Here are some assumptions made in this script:
#        o Most servers are 64-bit, but there are still 32-bit clients
#        o This script calls Java, and Solaris and HP-UX uses a special flag
#          ("-d64") that specifies 64-bit mode for Java when installing 64-bit
#        o The "-d64" option is only valid for Solaris and HP-UX
#        o SHLIB_PATH is only used for HP-UX (but it also uses LD_LIBRARY_PATH)
#        o LIBPATH is only used for AIX
#        o LD_LIBRARY_PATH is used by Linux, Solaris and HP-UX
