Name: xypic Version: 3.3 <1996/12/19> Description: Xy-pic is a package for typesetting graphs and diagrams. It is structured as several modules, each defining a custom notation for a particular kind of graphical object or structure. Example objects are arrows, curves, frames, and colouring/rotation on drivers that support it; these can be organised in matrix, directed graph, path, polygon, knot, and 2-cell structure. Xy-pic works with most formats, including LaTeX, AMS-LaTeX, AMS-TeX, and plain TeX, and has been used to typeset complicated diagrams from many application areas including category theory, automata theory, algebra, neural networks, and database theory. Keywords: diagram, picture, graph, arrow, curve, commutative diagram. Author: Kristoffer H.
