    Created ChangeLog.tty, README, CompileReDraw.CM, ListReDraw.CM.
    Eliminated PrintFloat (can't find .BR or .BCPL file!); now prints height
        to two decimal places.
    Changed ec in font directory from 177b to 377b, for the sake of those
        printers that look at it.
    Called it version 2.2. (Version 2.1 was created by Lyle Ramshaw by
        OEDITing the .RUN file for version 2.0 to implement the change from
        177b to 377b mentioned above).
