| 23 | * This class implements a Text_Wiki_Parse to find sections marked as code | |
| 24 | * examples. Blocks are marked as the string <code> on a line by itself, | |
| 25 | * followed by the inline code example, and terminated with the string | |
| 26 | * </code> on a line by itself. The code example is run through the | |
| 27 | * native PHP highlight_string() function to colorize it, then surrounded | |
| 28 | * with <pre>...</pre> tags when rendered as XHTML. | |
