# Example for calculating overlaps of primitive basis functions for almost
# coinciding nuclear coordinates, using the key CALCOVERLAPONLY. ADF will stop
# after the calculation of these overlaps. The overlap is printed in the output,
# but is also present on TAPE15 in binary format in Matrices%Smat.
# Could be useful for external programs like SHARC.
