class_docstr: Wrapper around the standard 'getopt()' module that provides some
  handy extra functionality:
    * short and long options are tied together
    * options have help strings, and help text can be assembled
      from them
    * options set attributes of a passed-in object
    * boolean options can have "negative aliases" -- eg. if
      --quiet is the "negative alias" of --verbose, then "--quiet"
      on the command line sets 'verbose' to false
code: def print_help(self, header=None, file=None):
      if file is None:
          file = sys.stdout
      for line in self.generate_help(header):
          file.write(line + "\n")
  
imports: import sys, string, re
  import getopt
  from distutils.errors import *
label_desc: Use image node_id 14 for calling the FancyGetopt obj's underlying member method code with example usage: obj.print_help(header, file) without return types
