			MathTime 1.1 (short notes)
			--------------------------

The ZmathTime package from Loek Helminck is build on top of the
MathTime fonts. The lowest layer consists of the following fonts:
  mtex.tfm 			mtex.pfb
  mtsy.tfm			mtsy.pfb
 rmtmi.tfm		       rmtmi.pfb
  mtmi.tfm                      mtmi.vf

Unfortunately the checksums of the MathTime fonts are incompatible
with ps2pk. So to avoid lots of complaints you have to change the
checksums by editing the PL files. You can compute the ps2pk checksum
with the cs utility provided in src. For example to get the octal 
value you need in your mtex.tfm you run:
   cs -o mtex.afm

Between the checksums as provided by the MathTime 1.1 fonts and those
computed by ps2pk I found the following differences:

	          tfm         vf          pk
	 -----------------------------------------
	 mtex 13111454533     -        21533520063
	 mtsy 13111454440     -        31005005314
	rmtmi 13111454440     -         5271001536
	 mtmi 26441631172 26441631172       -

Check first what your checksums are and if they differ too then change
the TFM files with the following algorithmic description:

        cd TEXROOT/tfm
	foreach f (mtex mtsy rmtmi) {
           tftopl $f.tfm $f.pl
           edit $f.pl by hand (take values from last column)
	   pltotf $f.pl $f.tfm
        }

Now you can build the zmathtime fonts with `make zmathtime'.  The
zmathtime package builds on top of the fonts mentioned above by
providing an extra set of virtual fonts:
   zmt{mr,mi,mbi,mb,sy,bsy}.tfm
   zmt{mr,mi,mbi,mb,sy,bsy}.vf

So you can use your old fonts and the new LaTeX2e fonts at the same
time (not explained in the package ...).
