Contains routines for contraction without dgemms. PLEASE DO NOT MODIFY. Contains specific routines for contraction. The compiler flag -D__MAX_CONTR defines the maximum angular momentum up to which specialized code will be used. Default setting is d-functions. Increasing -D__MAX_CONTR produces faster code but might overburden the optimization capabilities of some poor compilers. This file contains specific code up to g-functions. If you need more look at cp2k/tools/hfx_tools/contraction/.
