Hi, Kay!

Thanks for this explanation.  So it can only open a .opi file from the
command line if it's already open in CSS?  That's not very useful to me.

Thanks for all of this!  And (the question I'm sure you get all the
time) when will Phoebus be ready for production use? :-)  It seems like
a very positive update project; I really look forward to it!  Thanks for
your effort on it!
