Computation Chemistry Integral Evaluation Library (development files)

 The Libint2 library is used to evaluate the traditional (electron
 repulsion) and certain novel two-body matrix elements (integrals) over
 Cartesian Gaussian functions used in modern atomic and molecular
 theory. The idea of the library is to let computer write optimized
 code for computing such integrals. There are two primary advantages to
 this: much less human effort is required to write code for computing
 new integrals, and code can be optimized specifically for a particular
 computer architecture (e.g., vector processor).
 Libint2 has been utilized to implement methods such as Hartree-Fock
 (HF) and Kohn-Sham density functional theory (KS DFT), second-order
 Moeller-Plesset perturbation theory (MP2), coupled cluster singles and
 doubles (CCSD) method, as well as explicitly correlated R12 methods.
 This package contains the static library and header files.
