Multiple language support

[jparisu]

Hi there,

I have been trying to find a way to support multiple languages in my documentation project, but I did not manage to do so.
I have a documentation written in Spanish, but I have a lot of code as well, so all the key words (like for, while, etc.) appears as errors in my spelling.
How can I do to check spelling in these 2 languages?

Thank you
