56 | 6.21.5 Extending <tt class="module">optparse</tt> | |
57 | </H2> | |
58 | ||
59 | <P> | |
60 | Since the two major controlling factors in how <tt class="module">optparse</tt> interprets | |
61 | command-line options are the action and type of each option, the most | |
62 | likely direction of extension is to add new actions and new types. | |
63 | ||
64 | <P> | |
65 | Also, the <code>examples/</code> directory of the source distribution includes | |
66 | several demonstrations of extending <tt class="module">optparse</tt> in different ways: e.g. a | |
67 | case-insensitive option parser, or two kinds of option parsers that | |
68 | implement ``required options''. | |
