Documentation

It was noted that with the increasing number of sequencer scripts and commands it has become hard to find things. I was agreed that the objective is to fully integrate all the basic scripts and commands in to a data-base and add things like the (short and long) description of how a script works, and if a script is a general or often used script etc., to the scripts themselves so that documentation such as web pages can be generated automatically with update information every time people look at the web pages. A first version for ALFOSC has been made where commands can be selected depending on any combination of Observing Mode, Command Type, Usage and Description. As part of this work, various minor updates to the descriptions of the individual sequencer commands were made.
