This is the 64-bit exectuable for topdrawer for linux.
It was compiled and statically linked using gfortran/gcc-8.3.0.

The only output devices contained in this executable are 
POSTSCRIPT and TEKTRONIX:  none of the other options contained in the 
original SLAC Unified Graphics System library have been built
since I lack access to the necessary hardware to test them.

POSTSCRIPT = produces a Postscript output file suitable for embedding
in, e.g. TeX or LaTeX.

TEKTRONIX = direct-to-screen output into a Tektronix 4010 window.
