AUTO INSTALL
  The auto install program will test to determine whether you already have
a macro named {Alt-Z}. IF SO, then the install program will rename 
existing {Alt-Z} to ";old alt-Z", so that it will be preserved. After you
install the program you may then either rename the NEW {Alt-Z} (see
FWZdoc.fw3) or rename or delete the old {Alt-Z}. 
Auto Install also sets certain DOS paths that are required.
