--------------------------------------------------------
  ATTENTION: Do not delete the Makefile.orig files!!!
            The compilation is based on them.
--------------------------------------------------------


1. cd to the 'source' directory.  There you will find
   the controlling Makefile for compiling ltplus.
      cd source

2. Edit the Makefile to configure for your system.

3. cd .. (to LTPlus main directory)

4. Compile the entire package:
   
     gmake4.2

4. You will run LTPlus from /usr/local/grass42/ltp/bin
   (see below)

   LTPlus currently works now on 8bit as well as 16/24bit-X11-Systems.

   (many, many thanks to Carl Anderson!!  candrsn@mindspring.com )   

5. Documentation about first LTPlus configuration you find in
   /usr/local/grass42/ltp/documentation/
   or here in the source code
         lt03.ps: description of config-file
         etc.


--------------------------------------------------------------
When running the program, you MUST use the -m option on ltpgo

If graphics end up looking distorted you may need to 
set the environment variable:  BITSWAP.  This is currently needed
on Suns.  In fact, BITSWAP can be set to either TRUE or FALSE;
either one may be required under diferent scenarios.  If graphics
are broken up, first try setting it to TRUE, and if that doesn't
work, then try FALSE.

It is  recommended that you create a shell script similar to the following
which is used to run ltplus:


-----------------------------------------------------------------
#!/bin/csh -f
export LTPHOME=/usr/local/grass42/ltp

# if Bitswapping is needed
#setenv BITSWAP TRUE
#setenv BITSWAP FALSE

/usr/local/grass42/ltp/bin/ltpgo -m
