the language is 'Tcl', short for tool command language.  'Tk' is short for
toolkit, essentially a bag of Tcl commands which provide the graphical (UI)
elements like buttons.

non-graphical stuff gets run/executed by 'tclsh' -- the Tcl shell, while UI
stuff gets executed by the 'wish' program -- the windowing shell.

most people use '.tcl' as extension for both UI and terminal-only scripts (I
don't).  after a default installation, any 'something.tcl' can be double-clicked
to run (and you will probably never notice any difference to a compiled s/ware).
