davidw rumor has it that Alcatel uses Tcl/Tk for data acquisition and text processing.
Jamesbe Actually Alcatel does use Tcl and Tk for many internal testing applications. It is used for testing routers and switches in almost all carrier grade products that Alcatel produces. Integration with Ixia and Spirent test gear has been developed for mission critical testing.
I am also aware of sell able product that is produced at Alcatel that uses TCL/TK.
