Indeed, SQLite is merely a Tcl extension that &quot;escaped&quot; into the wild.  SQLite no longer depends on Tcl to run, but it does still depends on Tcl for its make process and for testing.  The SQLite development team also depends on tools written in Tcl&#x2F;Tk for tasks such as editing and collaboration.<p>Where Tcl to die, SQLite would die with it.  Fortunately, both outcomes seem unlikely.<p>Some of us are old enough to remember the frequent prognostications that &quot;unix is dead&quot; and was being replaced by more modern OSes like VMS or OS&#x2F;2.  How&#x27;d that work out?
