name borceux category Package shortdesc Diagram macros by Francois Borceux. longdesc The Diagram macros realize the construction of diagrams as those longdesc appearing in category theory texts. The user gives the list of longdesc vertices and arrows to be included, just as when composing a longdesc matrix, and the program takes care of computing the dimensions of longdesc the arrows and realizing the pagesetting. All the user has to do longdesc about the arrows is precising their type (monomorphism, pair of longdesc adjoint arrows,\ldots) and their direction (north, south- longdesc east,...): 12 types and 32 directions are available; see figures~1 longdesc and 3 for exhaustive lists.
