answer:I always use some form of version control, it is very useful for numerous reasons. I’ve given Git and Mercurial try outs but after hearing from the developers of Ask-public that they’ve been using Bazaar with success, I decided to give it a try. I’ve now completely switched my personal code to Bazaar and have migrated or recreated most of the repositories from Subversion to Bazaar. I digress. Anyway, if you don’t use version control now, you should start. Its one of those habits that is good to get into much like unit testing (which some find harder to make habitual). If you do development work long enough it will save your ass one day.
