I think I know the answer to this one, but I will ask anyway. Is there a document which documents the design and implementation of the notebook? And yes, I am aware the most accurate document is the source code! As a second question, has anyone ever written any code which simulates real users randomly logging in, and doing "normal" things? (Code like this is written to test web servers - see for example http://curl-loader.sourceforge.net/) Dave -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
