Am I mistaken.
The sage-update script gives an idea of how sage is upgraded from a SAGE_SERVER: - download the new install script - download the new list file. The list file contains all spkgs with their version numbers. It is from it that sage knows which packages have been updated and why specifying version numbers for now is necessary. - download the new deps file - download the newest_version script. newest_version determines the latest version of an spkg you have installed locally. - check the contents of your list file against your `ls spkg/standard/`. Anything that is in list and not in the output of ls is downloaded. didier --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
