<H3 CLASS=ABSTRACT>Abstract:</H3><P CLASS=ABSTRACT>Xy-pic is a package for typesetting graphs and diagrams using
Knuth's TeX typesetting system. Xy-pic works with most of the
many formats available, <I>e.g.</I>, plain TeX, LaTeX, and AMS-TeX.
Several styles of input for various diagram types are supported; they
all share a mnemonic notation based on the <em>logical composition of visual components</em>. This guide concentrates on how to
typeset "matrix-like" diagrams, such as commutative diagrams,
in the following style:

Such diagrams have the following characteristics:
<UL>
<LI>Specified as a matrix of entries that are automatically aligned in
rows and columns.
<LI>Any entry may be connected to any other entry using a variety of
arrow styles all rotated and stretched as required.
<LI>Arrows may be decorated with labels that are tied to a specified
point along the arrow and extend in a particular direction; and
arrows may be paired, cross, and visit/bend around other entries "on
the way."
<P>
</UL>
Several other styles of input are supported; a short survey of the
possibilities is included last at the end along with information on
how Xy-pic can be obtained.
