[no author was given in the sources]
 
This message is in response to your request for my METAFONT source code
for the planetary symbols.  I thank you for your interest, and I hope
that somebody out there may actually find these useful.
 
The rest of this message contains:
\begin{itemize}
\item  command procedures to set up and run computer-modern METAFONT;
\item  font drivers at 10, 9, 8, 7, 6, and 5 pt;
\item  source code for the symbols themselves;
\item  a TeX file to define the symbols.
 \end{itemize}
 
 
The basic scheme is that one of the driver files (e.g. CMASTRO10.MF) is
input to CMMF on the command line; it sets up values for the standard
computer modern variables, then inputs SYMBOLS.MF.  This in turn defines
more symbols, then inputs the source code for each character in turn.
This is the same sort of scheme used by Knuth, particularly in the math
fonts, from which all this was taken.
 
You may find that the arrows for Uranus and Neptune are very slightly
lopsided.  I haven't had the time to investigate this; you are welcome to,
of course.
 
[
NOTE: the sources as they arrived were set up for a VMS site; I have
created two Unix shell scripts (`dozero.sh' and `dohalf.sh') to stand
in for the similar DCL scripts. Otherwise the files should be the same
under any system.
 
I have also provided a different use of the fonts in `astro.sty', a
LaTeX style file which uses the fonts at magstep 4  (made by
dofour.sh) as nice big pictures (see demo.tex).
