This document delineates the environment variables that may be set
before running these tests.

LTPROOT
 - The full path leading up to the ``testcases'' directory.

REFERENCE_PLATFORM_HOST
 - The hostname or IP address of the reference platform for SSL
   protocol tests.

REFERENCE_PLATFORM_USERNAME
 - The username for the test account on the reference platform.

REFERENCE_PLATFORM_PASSWORD
 - The password for the test account on the reference platform.

REFERENCE_PLATFORM_SUCCESS_STRING
 - When the test client successfully logs into the test server, this
   is the string that the test client should expect to receive.  This
   string should not be seen in the fail case.

The reference platform should have a test user account and should
accept SSH logins.  For example, if the test username is ``ealuser'' and
the password is ``1qaz2wsx3edc'', then the environment variables might be 
set up like so:

export REFERENCE_PLATFORM_HOST=x.x.x.x
export REFERENCE_PLATFORM_USERNAME=ealuser
export REFERENCE_PLATFORM_PASSWORD=1qaz2wsx3edc
