P.S.: There's a horribly outdated README.txt (with still uppercase SAGE, and among other flaws, telling one could move the Sage tree anywhere): http://files.sagemath.org/linux/32bit/README.txt I guess the ones in the other bdist subfolders aren't much better. On the other hand, the web page itself (i.e., index.html) gives recent info on uncompressing the various(?) formats offered. There we could also add some short info on how to proceed after downloading. More worms escaping the can... (I'd say Pandora's box though.) -leif P.P.S.: Just noticed in the mentioned description of compression formats, there's "everything" but what we currently solely offer (namely .tar.bz2, for whatever reason)... 8-) Nearly the same for the linux/64bit/ folder, including README.txt (while there's also some left-over beta rpm, and also an obsolete sage-x.y.z-sage.math.washington.edu-x86_64-Linux.txt). CC'ing Harald, as I'm not going to open an issue on GitHub. Maybe we should also forward this to sage-devel, but with a more appropriate title. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
