If you have trouble running this demo, remember that the ZIP file
should be unzipped with the -d flag set, like this:

pkunzip -d mig29 <ENTER>

This will cause PKUNZIP to create the original subdirectories and
place the files into them. If you don't want to unzip the files
again, you can create a subdirectory called D on your disk with
the command:

md d <ENTER>

then copy the files CDEMO, COCKPIT, DEMOG, DEMOS and TITLE into
this directory. You can then delete the copies of these files
from the main directory. To run the demo from the main directory,
type:

mig29 <ENTER>
