  manifest.js - Writes a custom XML manifest for each executable/library
  5 command line options must be supplied: 
  name      - Name of the executable/library into which the mainfest will be 
              embedded.
  version   - Version of the executable 
  arch      - Architecture intended.
  exe_level - Application execution level. 
              [asInvoker|highestAvailable|requireAdministrator]
  outfile   - Final destination where mainfest will be written.

  Example:  
  cscript manifest.js name=mysql version=5.0.32 arch=X86 type=win32 
                      exe_level=asInvoker outfile=out.xml
