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 GNUmakefile exists, and typing ''make'' will compile the MRCC program and link the MRCC executables into the MOLPRO bin directory which from here 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.
