Hi, Matt!

Thanks for the recommendation!  caQtDM looks quite interesting.

A concern for me is that I often want to include a GUI with EPICS-based
software I write.  To date, I've always included MEDM screens (i.e.,
.adl files).  I've noticed, however, that some modules include more than
one type of GUI.  For example, areaDetectors's ADCore has .adl, .edl,
and .opi files.  caQtDm's native GUI file format seems to be .ui files.
That makes four different GUI formats.  I'd hate to have to maintain
more than one GUI.

So, how do I provide a useful GUI and at the same time avoid maintaining
more than one?  You mention that adl2ui works well, but it sounds like
you would plan to convert MEDM screens once to .ui files, and then
continue in .ui files from there.  Is there a way to automatically
generate .adl, .edl, and .opi files from .ui files?  Or is there a
consensus forming around .ui files such that it would be reasonable to
just provide .ui files where I previously provided .adl files?
