YOU MUST HAVE INSTALLED THE BINARY DISTRIBUTION OR INSTALLED AND
BUILT THE SOURCE CODE DISTRIBUTION BEFORE RUNNING VALIDATION TESTS
IF YOU ARE USING THE DATA IN THE `test_data' TAR ARCHIVE YOU
MUST INSTALL THAT AS WELL.

You can run the tests and create base line test data
with `$OPD_ROOT/scripts/master_validate.sh'. Execute this
with no parameters for instructions.

If you have the source code distribution you can run the validation
script from the `Makefile' in `$OPD_ROOT/build'. 
Do a `make' with no parameters in that directory for instructions.
The tests must be run under X-windows.

If no errors are discovered you will see a message similar
to the following at the end of the test:

___ Test Summary ___
Did 97 tests comparing 524 files.
8881729 values were compared with no errors.
The fewest compares for one file checked 888 values.
There are no differences between the base line validation log
`/usrb/dist/ftp/opd-0.1/validate/base_log' and this log
`/usrb/dist/ftp/opd-0.1/validate/validation_log'.

This above is for both int16 and floating point tests. The directories
of the logs may be different on your system. The same message
should appear at the end of `$OPD_ROOT/validate/validation_log'.

The Developer's manual includes instructions for creating new tests.
