A file mrcc.tar.gz will be provided by by M. Kallay. This file should be copied into directory MRCC under the main MOLPRO directory. In this directory, a Makefile exists, and typing ''make'' will compile and install the MRCC program. The executables will be copied into the MOLPRO bin directory and are automatically called by MOLPRO. Orbitals and other input information are communicated via external files, transparent to the user. Once the program is installed, please run ''make mrcctest'' in testjobs directory.
