The package comes in two parts: first, some macros that are generally applicable to drawing diagrams in LaTeX; and second, macros specific to drawing category theory diagrams.
The package was written for LaTeX 2.09, but continues to work under LaTeX 2e; however, an updated version, that uses pict2e, is also available.
The author is John Reynolds.
