| * |
| * Less intrusive loading and usage of SyntaxHighlighter: |
| * |
| * Changes: |
| * * No "brush" (language syntax) is loaded by default |
| * * With standard SyntaxHighlighter code blocks must have name="whatever" (and options |
| * are passed as 'class="html:collapse"'). Assigning a name to a pre is not valid |
| * hence a workaraound is used here: code blocks must have class 'syntax-highlight'. |
| * * Note that without base2 language loading must be done by the user |
