__DATA__
|
|
|
|
This is the text page for the rules.
|
|
This is a single paragraph.
|
|
With a link to [[other paragraphs]].
|
|
|
|
* This is a list
|
|
with three items.
|
|
* Second item.
|
|
* Third item with a link: [[list items]].
|
|
|
|
We also have numbered lists:
|
|
|
|
1. We use something like setext...
|
|
2. But we ~extend~ it.
|
|
3. **Really we do!**
|
|
|
|
The default are non-strict setext rules.
|
|
Therefore we also allow
|
|
//multi-word emphasis// and
|
|
__multi-word underlineing__, and we also
|
|
allow the similar /single/ _word_ *rules*.
|
|
|
|
I think that's all the rules we [[implemented]].
