Since the last update to the commands was quite a while ago and there are now a lot more CEL/CELX commands available an update was long overdue.
Since Celestia version 1.6.0 the original listing of only 35 CEL commands has been expanded to 51 CEL commands and for some commands, new arguments have been added.
Marco Klunder was so kind to provide this new complied information.
The Document will be organized into subsections to be easily updated in case new functions are included:
