 I did a little experiment.  First, I created an X application and
 got its id with xwininfo.  Then I created a Tcl container frame with

         frame .foo -container 1
         pack .foo -fill both -expand yes
         winfo id .foo

 Then, I run "xreparent (window-id) (.foo-id)" (program
 given below).

 This works: the X window appears in the Tk frame; I tried it with
 xterm, Netscape, and rxvt. The problem is: the geometry management
 doesn't work.  The embedded window never gets resized when the Tk
 window or frame changes size.  If I embed another Tk toplevel with the
 "-use" command line option, things work OK for that Tk toplevel.

 Any ideas?  The man page for "frame -container" claims that the frame
 does all the things with resizing and colors that a toplevel window
 would expect.
