Are there different versions of *.mf files? I am trying to build
msym and msxm fonts in pk format at 406dpi and I just picked up
the *.mf files from the labrea.stanford.edu archive and when I run 
version 1.5 of METAFONT on one I get this:-

   cmmf '\mode:=agfa;' input msxm5
   This is METAFONT, C Version 1.5 (no base preloaded)
   (mfs/msxm5.mf
   American Math Society Symbols 5 point -- 1st extra font
   >> fontidentifier
   ! Isolated expression.
   <to be read again>
                      "MSXM"
   l.3 fontidentifier "MSXM"
                            ; ptsize=5;
   ? X
   Output written on msxm5.2602gf (0 characters, 148 bytes).
   Transcript written on msxm5.log.

So I had a look at cminch.mf which I CAN build and the top 10 lines look
like this:-

   % Computer Modern Inch-High Sans Serif Bold Extended Caps and Digits
   if unknown cmbase: input cmbase fi
   numeric Pt#; 250/36Pt#=1in#;
   font_identifier:="CMINCH"; font_size 10Pt#;
   
   u#:=22/36Pt#;      % unit width
   width_adj#:=22/36Pt#;    % width adjustment for certain characters
   serif_fit#:=-9/36Pt#;    % extra sidebar near lowercase serifs
   cap_serif_fit#:=-11/36Pt#;  % extra sidebar near uppercase serifs
   letter_fit#:=0Pt#;    % extra space added to all sidebars

whereas the top 10 lines of msxm5.mf look like this:-

   "American Math Society Symbols 5 point -- 1st extra font";
   % based on "old" Computer Modern
   fontidentifier "MSXM"; ptsize=5;
   
   pww=5/36; % small hairline width
   puw=8/36; % uppercase hairline width
   pscorr=.7/36; % some stems to be this much thinner
   pbow=.7/36; % baseline serifs to be bowed by this much
   phcorr=.5/36; % some hairlines to be this much thicker
   pdot=22/36; % dots

the same sort of data is in them, eg "font_identifier" vs. "fontidentifier"
but in a different format - what goes on here? Do the *.mf files from the
American Math Society have differences from the cm fonts.

Any help/pointers welcome.

cheers,
gerry
