Class OptionContainer

Known Subclasses:

OptionParser

Abstract base class.

Class attributes:
  standard_option_list : [Option]
    list of standard options that will be accepted by all instances
    of this parser class (intended to be overridden by subclasses).

Instance attributes:
  option_list : [Option]
    the list of Option objects contained by this OptionContainer
  _short_opt : { string : Option }
    dictionary mapping short option strings, eg. "-f" or "-X",
    to the Option instances that implement them.  If an Option
    has multiple short option strings, it will appears in this
    dictionary multiple times. [1]
  _long_opt : { string : Option }
    dictionary mapping long option strings, eg. "--file" or
    "--exclude", to the Option instances that implement them.
    Again, a given Option can occur multiple times in this
    dictionary. [1]
  defaults : { string : any }
    dictionary mapping option destination names to default
    values for each destination [1]

[1] These mappings are common to (shared by) all components of the
    controlling OptionParser, where they are initially created.
