The above adds an action called `action_name`, which, when requested, outputs the text `Hello, World!`.
### `register_save_preprocessor($function)`
Registers a function to be called every time a page is edited. The function will be passed the following parameters:
1. A reference to the pageindex entry that is about to be saved.
2. The new text that is to replace the old text.
3. The old text that the new text is going to replace.
If you make the function that you pass here take the new text that is to be saved in as a reference, you may alter it before it is saved to disk.
### `page_renderer`
You probably want your module to output a nice user-friendly page instead of a simple text-based one. Luckily, Pepperminty Wiki has a system to let you do that.
