plugin_description "Apply syntax highlighting to a code block"
def self.help_text
%{
You can use `<typo:code>` to include syntax-highlighted code blocks. Example:
<typo:code lang="ruby">
class Foo
def bar
"abcde"
end
end
</typo:code>
This uses the Ruby [Syntax](http://syntax.rubyforge.org/) module. Options:
* **lang**. Sets the programming language. Currently supported languages are
`ruby`, `yaml`, and `xml`. Other languages will format correctly but will not
have syntax highlighting.
* **linenumber**. Turns on line numbering. Use `linenumber="true"` to enable.
* **title**. Adds a title block to the top of the code block.
* **class**. Adds a new CSS class to the wrapper around the code block.
}
