This is probably an extremely basic question, but I can't figure it out.
I got the Sage source code from a .tar file from the download link here: http://boxen.math.washington.edu/home/sagemath/sage-mirror/src/index.html
I unpacked the tar file using 7-zip and got the directory containing some files, the .hg folder, and the spkg folder. I am told that .spkg is just a tar file, but I can't seem to open them up. Could someone walk me through the steps for Windows?
Thanks
