mff fonts based on the CMR programs.

    I have never been able to decide exactly what to call these fonts.  I
    have always thought of Computer Modern, CM Sans-Serif and CM Typewriter
    as separate families in one CMR "meta-family", but that may or may not
    jar with your understanding of Knuth's intent... :-)

    From a Platonist's point of view, CM is a perfectly-formed concept of a
    typeface, floating about "out there" and what I have here is merely a
    new implemntation of it.  So calling it (something)CM is reasonable.  To
    fit in with Karl Berry's naming system, they should all bre prefixed
    with a foundry letter; I shall use "f" ("freeware") for now.

    Thus we have 
	fcm	Computer Modern	 very similar to cmr or cmti
	fcm?s	CM Sanserif	 very similar to cmss
	fcm?t	CM Typewriter	 very similar to cmtt
	fcm?st	CM Sanserif Typewriter

    e.g., 	mff -ffcm fcmr12 fcmrs12 fcmrst12

    There are two obvious ways to store these files:

     --	put the mf file in /usr/local/lib/tex/mf/inputs and fcm.mff in
	a global mff file directory such as /usr/local/lib/tex/mf/mff; or

     --	put the the fcm.mf files in their own directory and put
	the fcm.mff file there as mff.rc (then the -f option is not
	needed so long as you cd there first).
