AUCTeX ⇒ Question on adding custom commands to AUCTeX

[sevillad]

Hi,

I am trying to create a command which runs latex on a poster .tex file, then converts the dvi to a pdf. I have managed to do it more or less, by adding to "Tex Command List" in the options the following command:

latex %s && dvipdf %s

However, if some error occurs during the first part, for example a missing file, latex would give a prompt; I would prefer if an error message was given, as when I run the usual LaTeX command by AUCTeX.

Is there a way to tell AUCTeX to detect a poster situation (for example by looking at the documentclass) and choosing my custom command when I select LaTeX after C-c C-c?

Thanks a lot,

David
