+"Maintainer:  Joshua Rahm <joshuarahm@gmail.com>
+"Notes:       Add the special comment line "// profile: " somewhere in the file

+"             checking the file. The defalt behavior is to pick the profile
+"             based on the entries of dictionary g:syntastic_glsl_extensions
+"             or a default dictionary if that variable does not exist
