---  Making and Installing HF-Lab on a Unix System.  -----

HF-Lab should compile without trouble using GCC. I have not tried other
compilers. Go to the /src directory and edit the makefile to reflect the
location of your X11 libraries, and whatever flags need to be set for your
system. Then type "make" and you should end up with an executable called
"hlx". I have been able to compile it on Solaris, IRIX 5.x, Linux, HP-UX,
SunOS, and Ultrix.  Version 0.85 apparently works on a Dec Alpha (thanks to
Neil Schellenberger).

After compiling, move the executable and the 'hf-lab.hlp' help file to their
final destinations and set the environment variable HFLAB.HLP to be the
full pathname of the help file.  For example, add this to your .login:  

  setenv HFLHELP /usr/local/hf-lab/hf-lab.hlp

Personally I run the "bash" shell under Linux 1.2.13. I moved hlx and
hf-lab.hlp to /home/beale/bin and I added this to the .bash_profile in my
home directory:

   HFLHELP=$HOME/bin/hf-lab.hlp
   export HFLHELP


Now, type "hlx" and off you go. Try running the sample script files (*.scr)
in the scripts/ directory to get ideas. I also suggest reading the rest of
the documentation at some point.
