C     Version 4.45  01/22/01


Before anything is compiled, several declarations in the Makefile
may need to be uncommented for some machines.


To create plot library libPlt.a (single precision) you can normally just type:
  % make
provided the file Makefile is linked to Makefile.SP, or 
  % make -f Makefile.SP

To create plot library libPltDP.a (double precision version):

Use the make file Makefile.DP, either link it to Makefile or use this line
  % rm *.o
  % make -f Makefile.DP
this makes a library libPltDP.a, with the single-precision files (if any)
being removed first.  You may need to set compiler flags for your system, 
check the Makefile.DP file.

If you don't have a file Makefile.DP your alternative is to to this:
  go into the Makefile and uncomment the line 
#PLTLIB = libPltDP.a
  set the DP flag for your compiler (uncomment appropriate line)
  % make


To install plot library libPlt.a:
  check the Makefile for proper install options and destination for your system
  % make install


To create test, example and color selection programs (all optional):
  % make test


OR, go into the examples directory and do a:
  % make

if you want to put the examples in the parent library directory as well:
  % make test



To set black-on-white video, define Unix variable as follows:
  % setenv XPLOT11_BACKGROUND white


To restore white-on-black video:
  % unsetenv XPLOT11_BACKGROUND
