-.SH NAME
-classvariable \- create link from local variable to variable in class
-.SH SYNOPSIS
-.nf
-package require tcl::oo
-
-\fBclassvariable\fR \fIvariableName\fR ?\fI...\fR?
-.fi
-.BE
-.SH DESCRIPTION
-The \fBclassvariable\fR command is available within methods. It takes a series
-of one or more variable names and makes them available in the method's scope;
-those variable names must not be qualified and must not refer to array
-elements. The originating scope for the variables is the namespace of the
-class that the method was defined by. In other words, the referenced variables
-are shared between all instances of that class.
-.PP
-Note: This command is equivalent to the command \fBtypevariable\fR provided by
-the snit package in tcllib for approximately the same purpose. If used in a
-method defined directly on a class instance (e.g., through the
-\fBoo::objdefine\fR \fBmethod\fR definition) this is very much like just
-using:
-.PP
-.CS
-namespace upvar [namespace current] $var $var
-.CE
-.PP
-for each variable listed to \fBclassvariable\fR.
-.SH EXAMPLE
-This class counts how many instances of it have been made.
-.PP
-.CS
