Yes. There are multiple "tarballs" (actually wheel files) listed in checksums.ini and uploaded/downloaded to/from GitHub Releases and the Sage mirrors Together they cover the supported platforms.
Thanks. I confess that I misunderstood things about installing sage from source. I thought, for example, sage-10.4.zip contains all upstream source tarballs (files in /upstream) so that it can be used to install sage from it without internet connection. My question was based on the misunderstanding. Unzipping the zip file (first time for me) proved that I am wrong. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
