What does it mean when people say that Tcl is good for gluing
other applications together?

Supply examples here?

   * show uses of [open] "|process"

   * show uses of [exec]

   * show uses of [stacking commands]



[[ [cl] keeps teasing us with promises to write more on this subject...]]

[RS] also thinks of gluing as two or more powerful packages linked together with only a few lines of code - see [A little XML browser] where [tDOM] and [BWidget] needed only half a page for gluing into a useful app...
