How to build the SG (Scientific Graphics) library:
==================================================
    Modified  8/02/96 Ted Terpstra - added HP
	Modified  9/16/97 Marilee Thompson - use alias makesg


On a AIX computer:
to build library:
	> make libsg.a

for testing:
	> make tstp10

or:
	> alias makesg  make -f Make.AIX

On a DEC Alpha computer:
	> alias makesg  make -f Make.dec

On a Silicon Graphics computer:
	> alias makesg  make -f Make.sgi

On a HP computer (at General Atomics):
	> alias makesg  make -f Make.hp

On a Sun computer:
	> alias makesg  make -f Make.sun

Some SUN systems require the GNU C compiler available as gcc.
Ignore the "%LOC function treated as LOC" and other warnings.

To build the SG library and the XPLOT display program:
	> makesg xplot

To build the TSTP10 test program:
	> makesg tstp10


How to use programs with SG:
=====================================

1) set the environment variable TERMINAL_TYPE

  If you are using xterm:
	> setenv TERMINAL_TYPE XTERM

  If you are using a terminal emulator such as VersaTerm(PRO) on a Macintosh:
	> setenv TERMINAL_TYPE MAC

  If you are using XTC:
	> setenv TERMINAL_TYPE XTC
  To avoid acknowledging each plot in XTC:
	> setenv TERMINAL_INPUT NONE


2) set the environment variable PLOT

  To route plot output to your terminal:
	> unsetenv PLOT

  To route all plot output to the file "file.plt":
	> setenv PLOT file.plt

  To display plots on your terminal and save only those pages in the
  file "file.plt" where you type a "D" (or "d") at the beep:
	> setenv PLOT ",file.plt"

  To view the plots in "file.plt" on your terminal, if you have set PLOT
  to "file.plt" or ",file.plt":
	> xplot

  To view the plots in "file.plt" if you haven't set PLOT:
	> xplot file.plt


How to test the SG library:
==========================

To run the TSTP10 test program:
	> tstp10
	plot number (zero for all, -1 to quit)[0] ?0
	plot number (zero for all, -1 to quit)[0] ?-1
After the "0" command, the program should output several plots.

To run the TSTISO test program:
