OpenGL syntax highlighter for C and C++ source files.
Using the Pathogen plugin: (http://vimcasts.org/episodes/synchronizing-plugins-with-git-submodules-and-pathogen/)
From your ~/.vim directory:
git submodule add git://github.com/beyondmarc/opengl.vim.git bundle/syntax_opengl
If not using the Pathogen plugin: Add the opengl.vim file into your vim syntax folder (in most Linux distros: /usr/share/vim/vim<version>/syntax/after/(c|cpp)).
