Well, don't waste your time. I'm in favour of a complete rewrite. 1/3 length, splitting into sub-pages and so on. (e.g. a introduction doesn't have to mention all the packages, the install procedure and also not the ?? help function which tells you about the internals ... that's definitely no

2008-01-13 Thread Harald Schilly
Inside SAGE_BASE/examples/latex_embed is a small script for including SAGE code in latex files. This is in my opinion very useful for creating documents: reduces errors, no copy/paste and therefore takes less time to write tex files! Parsing and computing is separated and therefore no
