This gives a scope for converting the color eps's into monochrome
eps's using convert (which I guess, calls gs to do the job) exploiting
the shell escape of TeX compiler. The following test file worked
correctly in my setup:





  \immediate\write18{convert -monochrome color.eps mono.eps}



The \includegraphics command can be modified to accommodate the
\write18 function, so that the process becomes easier.
