We just installed/configured `SyntaxHighlight_GeSHi` after years of providing sample code without highlighting. We are a C++ library so nearly all of our sample code is C++.
We would like to set the default language to C++ and have GeSHi highlight all `<pre>` code to C++. Over time we will fix the highlighting issues.
Please provide a way to set a default language and have GeSHi highlight for it.
