# IMPORTANT NOTES - READ BEFORE RUNNING SCRIPT
#
# (1) ORACLE_HOME and ORACLE_OWNER can be defined in user's
#     environment to override default values defined in this script.
#
# (2) The environment variable LBIN (defined within the script) points to
#     the default local bin area.  Three executables will be moved there as
#     part of this script execution.
#
# (3) Define (if desired) LOG variable to name of log file.
