COCAL (COmpact Object CALculator) is a set of codes for computing initial data of numerical relativity simulations.
COCAL codes generate equilibriums and quasi-equilibriums of various relativistic compact objects,
including a rotating neutron star, binary neutron stars, binary black holes, and a black hole-toroid system.
Since COCAL codes are simple, it is easy to test various new ideas, features, formulations, etc.,
on the codes, such as new differential rotation laws, or strong magnetic fields. We introduce
COCAL codes, and present recent results on several data sets of compact objects.
