## Detailed Description

Symbol "MPQC.IntegralEvaluator2" (version 0.2)

IntegralEvaluator2_impl implements a class interface for supplying 2-center molecular integrals.

This is an implementation of a SIDL interface. The stub code is generated by the Babel tool. Do not make modifications outside of splicer blocks, as these will be lost. This is a server implementation for a Babel class, the Babel client code is provided by the cca-chem-generic package.
