- [doc getting-started:installation], or
- [doc getting-started:installation Custom link text]
- Updated Text_Wiki to 1.2.0
- Documentation should now pass XHTML validator
- Formatted DSN section so that it's easier on eyes
- The single quotes in <code type='php'> won't work anymore due to the Text_Wiki update. Use double quotes instead: <code type="php">. The single quotes have been converted to double quotes in documentation files.
- Modified the links in h1-h6 headings to use the same style as the headings.
- Some refactoring

* Parses for freelinked page links.
|
|

|
|
* This class implements a Text_Wiki_Parse to find source text marked as a
|
|
* wiki freelink, and automatically create a link to that page.
|
|
*
|
|
* A freelink is any page name not conforming to the standard
|
|
* StudlyCapsStyle for a wiki page name. For example, a page normally
|
|
* named MyHomePage can be renamed and referred to as ((My Home Page)) --
|
|
* note the spaces in the page name. You can also make a "nice-looking"
|
|
* link without renaming the target page; e.g., ((MyHomePage|My Home
|
|
* Page)). Finally, you can use named anchors on the target page:
|
|
* ((MyHomePage|My Home Page#Section1)).
