Querying and manipulating your option parser
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-Sometimes, it's useful to poke around your option parser and see what's there.
-OptionParser provides a couple of methods to help you out:
+The default behavior of the option parser can be customized slightly,
+and you can also poke around your option parser and see what's there.
+OptionParser provides several methods to help you out:
-``has_option(opt_str)``
- Return true if the OptionParser has an option with option string ``opt_str``
- (e.g., ``"-q"`` or ``"--verbose"``).
+``disable_interspersed_args()``
+ Set parsing to stop on the first non-option. Use this if you have a
+ command processor which runs another command which has options of
+ its own and you want to make sure these options don't get
+ confused. For example, each command might have a different
+ set of options.
+
+``enable_interspersed_args()``
+ Set parsing to not stop on the first non-option, allowing
+ interspersing switches with command arguments. For example,
+ ``"-s arg1 --long arg2"`` would return ``["arg1", "arg2"]``
+ as the command arguments and ``-s, --long`` as options.
+ This is the default behavior.
``get_option(opt_str)``
Returns the Option instance with the option string ``opt_str``, or ``None`` if
no options have that option string.
+``has_option(opt_str)``
+ Return true if the OptionParser has an option with option string ``opt_str``
+ (e.g., ``"-q"`` or ``"--verbose"``).

``remove_option(opt_str)``
If the OptionParser has an option corresponding to ``opt_str``, that option is
removed. If that option provided any other option strings, all of those option
