This is scat, a simple scattergram program, which we have found very
useful for all sorts of simple line drawing, with possible
labels etc. Scat writes plot(5) commands to the standard output.

1. 'make' compiles.
2. 'make install' installs.
3. 'scat -h' gives all the options.
4. See ../testgr for a number of graphics options.

5. Use the reldb programs to work on files like 'data'. This should
   not be done with options within scat.

Note that with the -E option, scat will generate plots where the
Y-axis label is "sideways", labels in the figure are centered etc.
For this to work, you need an extended plot-filter, such as the ones 
enclosed (in ../plot.src).

The enclosed Makefile assumes the user wants to link with the
plot-library, to generate plot(5) output. This is then normally
piped through the plot-filters (e.g. hpglplot or xplot, which are
enclosed. If none of the plot-stuff is available (notably in Xenix
and HP-UX), it should still be possible to link scat with hpglplot.o
or xplot.o and get a binary version of scat, which will work with that
single device. This is neither clean nor ideal, but it does provide
more usefulness.
