-.SH NAME
-rename \- Rename or delete a command
-.SH SYNOPSIS
-\fBrename \fIoldName newName\fR
-.BE
-.SH DESCRIPTION
-.PP
-Rename the command that used to be called \fIoldName\fR so that it
-is now called \fInewName\fR.
-If \fInewName\fR is an empty string then \fIoldName\fR is deleted.
-\fIoldName\fR and \fInewName\fR may include namespace qualifiers
-(names of containing namespaces).
-If a command is renamed into a different namespace,
-future invocations of it will execute in the new namespace.
-The \fBrename\fR command returns an empty string as result.
-.SH EXAMPLE
-.PP
-The \fBrename\fR command can be used to wrap the standard Tcl commands
-with your own monitoring machinery. For example, you might wish to
-count how often the \fBsource\fR command is called:
-.PP
-.CS
-\fBrename\fR ::source ::theRealSource
-set sourceCount 0
-proc ::source args {
- global sourceCount
- puts "called source for the [incr sourceCount]'th time"
- uplevel 1 ::theRealSource $args
-}
-.CE
-.SH "SEE ALSO"
-namespace(n), proc(n)
-.SH KEYWORDS
-command, delete, namespace, rename
