Ok, so a while ago I mentioned that I was going to try using a new way of working on my thesis using Subversion (a version control system predominantly used by computer programmers) and LyX (a document processor that uses LaTeX in an almost-WYSIWYG style to allow the author to focus on content alone rather than having to constantly worry about typesetting issues). And the result of the experiment? It’s been a resounding success. In this article I’m going to explain how to set up a working system so that you can work seamlessly across several computers, or collaborate with other authors without having to resort to fiddling around with USB disks or emailing yourself latest versions of documents. All using completely free software! How’s that?
