from other headers. Take it while it's hot. - To all those that lock source files: you'll burn in hell. Really. It'll be painful, dreadful and above all *long*. *Eternally* long. And there'll be Freddy Mercury and The Queen playing, *all the time*, day after boring, useless, sorrowful day. The song will be *``Radio Ga-Ga''*, in secula secularum amen. git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@1033 3ecf2c5c-341e-0410-92b4-d18e462d057c
