| Or, at the shell command line outside of Python: |
| |
| Run "pydoc <name>" to show documentation on something. <name> may be |
| the name of a function, module, package, or a dotted reference to a |
| class or function within a module or module in a package. If the |

| Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines |
| of all available modules. |
| |
| Run "pydoc -p <port>" to start an HTTP server on a given port on the |
| local machine to generate documentation web pages. |
| |
| For platforms without a command line, "pydoc -g" starts the HTTP server |
| and also pops up a little window for controlling it. |
