rename - Rename or delete a command
rename oldName newName
Rename the command that used to be called oldName so that it
is now called newName.
If newName is an empty string then oldName is deleted.
oldName and newName 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 rename command returns an empty string as result.
The rename 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 source command is called:
rename ::source ::theRealSource
set sourceCount 0
proc ::source args {
global sourceCount
puts "called source for the [incr sourceCount]'th time"
uplevel 1 ::theRealSource $args
}
