Sage patches written / reviewed

Graph tutorialLinear Programming TutorialSagebook
Some LP in Sage

If you have some code which could be useful to Sage, if you can help us review patches... Or even if you just have any question about Sage's graphs or the use of Linear Programming -- send me an email ! :-)
