Just out of curiosity: Is there a way to compile latex document with two document classes at once?

Suppose that I have a paper which start with line: \documentclass[preprint,authoryear,12pt]{elsarticle}

But finally I would like to compile it with such line: \documentclass[final,5p,times,twocolumn]{elsarticle}

Obviously I can replace these lines and compile file twice, but I wonder if there is any trick to avoid double compilation?


The easiest way is probably to create two dummy documents final.tex and draft.tex.





If you are using an IDE to compile make compiling the documents easier, there may be additional hoops to jump through (e.g., Kile: how to use shortcut to compile the root file directly?).
