The code-block directive provides syntax highlighting for blocks
of code. It is used with the the following syntax::
.. code-block:: CPP
#include <iostream>
int main( int argc, char* argv[] )
{
std::cout << "Hello world" << std::endl;
}
The directive requires the name of a language supported by SilverCity
as its only argument. All code in the indented block following
the directive will be colourized. Note that this directive is only
supported for HTML writers.
