:   '''tk appname''' ''?newName?''

If ''newName'' isn't specified, this command returns the name of the [Tk] application (the name that may be used in [send] commands to communicate with the application). If ''newName'' is specified, then the name of the application is changed to ''newName''. If the given name is already in use, then a suffix of the form "'''#2'''" or "'''#3'''" is appended in order to make the name unique. The command's result is the name actually chosen. ''newName'' should not start with a capital letter. This will interfere with option processing, since names starting with capitals are assumed to be classes; as a result, Tk may not be able to find some options for the application. If sends have been disabled by deleting the [send] command, this command will reenable them and recreate the [send] command.

<<discussion>>

Is there an effective way to ask the [window manager] what
appnames it knows?  This is an issue for [send] consumers,
of course.

[LV] What tkinspect does (well at least one version of it) is first
to check to see if winsend or dde is available, and if so, uses their
facilities to get the list of registered interpreters, and if not, then
it invokes [winfo interps] and uses that list.
