Installation of plplot for use with the Lattice C compiler.

A script is provided (make-all) to compile all of the routines and
create a Lattice compatible library.  You should examine this script
and the first part of plplot.h to become familiar with some of the
available options. (You might want to change some of the default
options).  To create the plplot library type

  execute make-all [FFP | IEEEF |IEEED]

where the options allow you to create Motorola fast floating point,
IEEE float, or IEEE double compatible libraries. The library is
created in the pllibs directory.  You may want to move the library
to lib: (the lattice directory containing the link libraries).
The libraries are named differently depending on whether you specify
FFP, IEEEF, or IEEED.
