I had some time to fix my old fault and make the Debian SLIME git archive on Alioth organized in its original way. This required unclean changes to the archive, namely renaming the branches `master' and `upstream' to `master.diverted' and `upstream.diverted' respectively, and replacing them with new branches. In case you use the archive, please delete your copy and fetch it from Alioth again. Sorry for the inconvenience.
