Look out for look4

This is a pick for those among us that are still hardcore “command line” only kind of guys. You know, the people that would rather type >>help plot instead of >>doc plot to get information on the plot command. Those of us that do this, know that the >>lookfor newton  command to find help that contains the keyword newton is slower than we would like. Jiro has come to our rescue with a new command: look4 .Once the original database is built, this is a very fast command with results that are very similar to what lookfor will get you, but in a small fraction of the time.
