### Valid command-line options

1. --oeints will cause CINTS to compute standard one-electron integrals only. Subdirectory Default_Ints had to be compiled in (it is by default).

2. --teints will cause CINTS to compute ERIs only. Subdirectory Default_Ints had to be compiled in (it is by default).

3. --oeprop will cause CINTS to compute one-electron property integrals (overlap, dipole moment, and integrals over electronic nabla operator) in AO basis. Subdirectory OEProp_Ints had to be compiled in (it if by default).

4. --fock is used by CSCF to cause CINTS to form the Fock matrices directly. Subdirectory HF_Fock and DFT had to be compiled in (it is by default). Do not use this option to run CINTS standalone, as it will try to read an intermediate file produced by CSCF.

5. --mp2 will cause CINTS to compute MP2 energy directly. Subdirectory MP2 had to be compiled in (it is by default).

6. --deriv1 will cause CINTS to compute first-order energy derivatives. Subdirectory Default_Deriv1 had to be compiled in (it is by default).

7. --deriv2 will cause CINTS to compute second-order energy derivative components and first-order derivative Fock and overlap matrices for solving first-order CPHF equations. Subdirectory Default_Deriv2 had to be compiled in (it is by default).

8. --mp2r12 will cause CINTS to compute non-standard MO integrals necessary to evaluate MP2-R12 energy with program MP2R12. Subdirectory MP2R12 had to be compiled in (it is NOT by default).

9. --r12ints will cause CINTS to compute non-standard AO integrals necessary to evaluate MP2-R12 energy. Subdirectories MP2R12 and R12_Ints had to be compiled in (they are NOT by default).

No command-line options will cause CINTS to evaluate and store standard one- and two-electron integrals. It is the default and most frequently used mode.
