Admin notes

The compilation was done as:

ml intel
mkdir ../build-2.3.1-intel2017; cd ../build-2.3.1-intel2017
../libint-2.3.1/configure --enable-shared --prefix=/common/debian/9.1/Compiler/intel/2017.4/libint/libint-2.3.1 --enable-1body=1 --enable-eri=1 --enable-eri3=1 --enable-eri2=1 --enable-contracted-ints --with-max-am=7 --with-opt-am=2 --with-cxxgen-optflags='-O3' CXX=icpc CC=icc
make install

Note - the various other things that are enabled are needed for molgw compilation. When enabled the libint compilation will take several days in serial and lead to a folder close to 7G in size. Possibly reducing the optimization level to O2 could cut the compile time somewhat.
