I so wish you were right! The programs you refer to like Singular are very simple and tiny compared to Sage. If things were so easy as you think, somebody would already have set things up so one can do things that way. Nothing is stopping anyway from doing that now. Let me repeat my remark to Gonzalo, but to you -- how would we actually do what you're suggesting? Could you lay out a somewhat detailed step-by-step plan, with estimates of how much work each step would be to carry out and maintain in the long run, which platforms would be supported, which packages would be removed when, etc.? -- William > > IMHO... > Dmitrii > > On Jan 22, 4:05 am, Robert Bradshaw <[email protected]> > wrote: >> On Jan 21, 2010, at 6:31 AM, Gonzalo Tornaria wrote: >> >> > On Wed, Jan 20, 2010 at 5:47 PM, Peter Jeremy <[email protected]> >> > wrote: >> >> My personal feeling is that it would be nice if some of the more >> >> generic >> >> packages (eg bzip, zlib, readline, mercurial) were moved out of sage >> >> and made explicit requirements. >> >> > +1 >> >> > I think Sage is mature enough now to slowly migrate toward this. >> > Besides, there can still be spkgs for those packages, and there could >> > be a sage-with-batteries-included tarball with dependencies included. >> >> What would be the advantage?
