    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.
