.SH NAME
xref \- generates a graphical cross reference picture for a class dictionary.

.SH SYNOPSIS
.I xref 
[class-dictionary]

.SH DESCRIPTION
.I xref
is a utility tool in the Demeter System/C++ which is useful for two purposes: 
.br
1. as a cross-reference program 
.br
2. as a class dictionary visualization tool.
.br
The edges of the class dictionary graph are represented 
by indentation. If a class is used more than once it will appear
on several lines and a vertical bar is used to indicate the equivalence
of all the class names which are connected by the vertical bar.
xref works also on parameterized class dictionaries.

The default
.I class-dictionary
is cd.cd.
