There's an old joke about how a burgler makes a cake. The recipe begins "To bake a cake, first steal two eggs". Of course, if you really don't want to do any baking in the first place, and all you really wanted was a simple pre-packaged cupcake, all this recipe stuff (not to mention hunting down the different ingredients needed) may be more trouble than it's worth. Occasionally, that's been my experience migrating from Windows to Linux. One such occasion has been my recent attempt to upgrade KDE from version 3.1 to 3.3.
