   I was a bit taken aback by Ralph Becker-Szendy's complaint about overlays
for MEX, IMP, etc.  I have done a number of them quite easily.  You just
grab an existing overlay file, preferably one that is close to what you
need, and you make your changes.  Admittedly, I have usually been making
rather simple changes -- supporting a different UART chip, adding a new
subcommand to SET, and so on.  Perhaps there are some other things one could
do with full documentation.  Also, I would be surprised if there is no
documentation floating around for MEX114 -- it seems to me that long ago I
saw such a file.  But not having needed it, I do not have a copy.
