borceux – Diagram macros by François Borceux

The macros support the construction of diagrams, such as those that appear in category theory texts. The user gives the list of vertices and arrows to be included, just as when composing a matrix, and the program takes care of computing the dimensions of the arrows and realizing the pagesetting. All the user has to do about the arrows is to specify their type (monomorphism, pair of adjoint arrows, etc.) and their direction (north, south-east, etc.); 12 types and 32 directions are available.
