                      !! SETUP NOTICE FOR SGI USERS !!

Please note that the 'LD_LIBRARY_PATH' environment variable must be
set up properly prior to executing 'pt_sgi'. If the path is not set
up properly then executing 'pt_sgi' will result in a series of error
messages printed by IRIX signalling that it cannot bind to 'libfltdata.so'.

Basically, you must set up the 'LD_LIBRARY_PATH' environment variable so
that it points to the sub-directory called 'openflight_libs':

Setup Instructions:

1) First, change to the sub-directory called 'openflight_libs' located 
   within the PolyTrans/SGI distribution directory.

2) Make note of the absolute path to the 'openflight_libs' directory. This
   can be done by invoking the 'pwd' command at a UNIX shell prompt.

   For example, "/usr/people/polytrans/openflight_libs' would be the directory.

3) Edit the file called '.login' in your home directory and add this line:

	setenv LD_LIBRARY_PATH /usr/people/polytrans/openflight_libs

   You should edit the path to the one noted in step # 2.

4) Log out of IRIX and log back in. If you type 'setenv' at a UNIX shell
   prompt then the 'LD_LIBRARY_PATH' environment variable should be set up
   as noted in step # 3.

5) PolyTrans/SGI should now run.
