-.SH NAME
-oo::singleton \- a class that does only allows one instance of itself
-.SH SYNOPSIS
-.nf
-package require tcl::oo
-
-\fBoo::singleton\fI method \fR?\fIarg ...\fR?
-.fi
-.SH "CLASS HIERARCHY"
-.nf
-\fBoo::object\fR
-   \(-> \fBoo::class\fR
-       \(-> \fBoo::singleton\fR

-.BE
-.SH DESCRIPTION
-Singleton classes are classes that only permit at most one instance of
-themselves to exist. They unexport the \fBcreate\fR and
-\fBcreateWithNamespace\fR methods entirely, and override the \fBnew\fR method
-so that it only makes a new instance if there is no existing instance.  It is
-not recommended to inherit from a singleton class; singleton-ness is \fInot\fR
-inherited. It is not recommended that a singleton class's constructor take any
-arguments.
-.PP
-Instances have their\fB destroy\fR method overridden with a method that always
-returns an error in order to discourage destruction of the object, but
-destruction remains possible if strictly necessary (e.g., by destroying the
-class or using \fBrename\fR to delete it). They also have a (non-exported)
-\fB<cloned>\fR method defined on them that similarly always returns errors to
-make attempts to use the singleton instance with \fBoo::copy\fR fail.
-.SS CONSTRUCTOR
-The \fBoo::singleton\fR class does not define an explicit constructor; this
-means that it is effectively the same as the constructor of the
-\fBoo::class\fR class.
-.SS DESTRUCTOR
-The \fBoo::singleton\fR class does not define an explicit destructor;
-destroying an instance of it is just like destroying an ordinary class (and
-will destroy the singleton object).
-.SS "EXPORTED METHODS"
-.TP
-\fIcls \fBnew \fR?\fIarg ...\fR?
-.
-This returns the current instance of the singleton class, if one exists, and
-creates a new instance only if there is no existing instance. The additional
-arguments, \fIarg ...\fR, are only used if a new instance is actually
-manufactured; that construction is via the \fBoo::class\fR class's \fBnew\fR
-method.
-.RS
-.PP
-This is an override of the behaviour of a superclass's method with an
-identical call signature to the superclass's implementation.
-.RE
-.SS "NON-EXPORTED METHODS"
-The \fBoo::singleton\fR class explicitly states that \fBcreate\fR and
-\fBcreateWithNamespace\fR are unexported; callers should not assume that they
-have control over either the name or the namespace name of the singleton instance.
-.SH EXAMPLE
-.PP
-This example demonstrates that there is only one instance even though the
-\fBnew\fR method is called three times.
-.PP
-.CS
-\fBoo::singleton\fR create Highlander {

-set h1 [Highlander new]
-set h2 [Highlander new]
-if {$h1 eq $h2} {
-    puts "equal objects"    \fI\(-> prints "equal objects"\fR

-set h3 [Highlander new]
-if {$h1 eq $h3} {
-    puts "equal objects"    \fI\(-> prints "equal objects"\fR

-.PP
-Note that the name of the instance of the singleton is not guaranteed to be
-anything in particular.
