Notes on Building From GIT, SVN or CVS
As you may have noticed, some of these slackbuilds download from GIT,
SVN or CVS and then build a package.
It's not unheard of for repositories to break from time-to-time,
therefore it's worth keeping a few of the older packages around in
case that happens. Then it's a fairly simple job of reverting to the
last one that worked.
The more complex the application, the more likely it is to break, so
there is always some trade-off between grabbing that latest feature.
