                     OptionParser

Parser for command-line and library use. The settings_spec specification here and in other Docutils components are merged to build the set of command-line options and runtime settings for this process.

Common settings (defined below) and component-specific settings must not conflict. Short options are reserved for common settings, and components are restrict to using long options.

Method Summary
	`__init__(self, components, defaults, read_config_files, args, *kwargs)` `components` is a list of Docutils components each containing a `.settings_spec` attribute.
	`check_args(self, args)`
	`check_threshold(self, level)`
	`check_values(self, values, args)` check_values(values : Values, args : [string]) -> (values : Values, args : [string]) Check that the supplied option values and leftover arguments are valid.
	`populate_from_components(self, components)` For each component, first populate from the `SettingsSpec.settings_spec` structure, then from the `SettingsSpec.settings_defaults` dictionary.

Method Details

init(self, components=(), defaults=None, read_config_files=None, *args, **kwargs)
(Constructor)

components is a list of Docutils components each containing a .settings_spec attribute. defaults is a mapping of setting default overrides.

Overrides:: optparse.OptionParser.__init__

check_values(self, values, args)

check_values(values : Values, args : [string])
-> (values : Values, args : [string])

Check that the supplied option values and leftover arguments are
valid.  Returns the option values and leftover arguments
(possibly adjusted, possibly completely new -- whatever you
like).  Default implementation just returns the passed-in
values; subclasses may override as desired.

Overrides:: optparse.OptionParser.check_values (inherited documentation)

populate_from_components(self, components)

For each component, first populate from the SettingsSpec.settings_spec structure, then from the SettingsSpec.settings_defaults dictionary. After all components have been processed, check for and populate from each component's SettingsSpec.settings_default_overrides dictionary.
