This file contains instructions for building the X11 version of xgraph.
When unpacked,  the source is distributed into three directories:

	xgraph-11	Top level source for the main program
	xgraph-11/xtb	A mini-toolbox for constructing the hardcopy dialog
	xgraph-11/ux11	A library of useful X11 programming utilities

A Makefile is provided in each directory.  Type "make" in the top level
directory to build the system.  The program assumes the machine already
has X11 libraries and include files installed in standard locations.
After a binary has been built,  you can move it to a standard location
and type "make clean" to remove object files and library archives.  The
manual page is in the file xgraph-11/xgraph.1.  This file can be moved
into standard manual page locations if desired.

A test program for xgraph is included.  To make this test program,  type
"make xgtest" in the top level directory.  Try the following command
to check out xgraph:

	% xgtest 7 -5.0 5.0 0.1 | xgraph

This should produce a graph with a series of parabolic curves.

Normally,  the program is compiled without debugging, profiling, 
or optimization flags.  You can change this by declaring the
appropriate flags in the Makefile variable CLEVEL in the top level
Makefile.

Other documentation files are included.  A summary of these
files is given below:

README.ANNOUNCE		Message submitted to comp.windows.x announcing
			the program and how to obtain it.

README.GENERAL		Important notes about differences and quirks
			of the program.

README.HARDCOPY		Documenation for writing your own hardcopy
			driver library.

README.INSTALL		This file.
