In the whole package "cost", there is 
- casdi (MRCI program), 
- dolo wich allows the localization of orbitals,
- exsci also named casdiloc which is a selected MRCI (quasi linear MRCI),
- noscf program to optimize orbitals (density matrices of states with different spin multiplicity or spatial symmetry),
- faiano, to transform a basis set in an ANO form (sometimes useful for the localization)
- etc...
