I just built and installed a Tcl package from source. Which I had to retrieve from archive.org because the historical location of the package appears to have disappeared from the net.

Why? Because I just started doing some work on an old-school Perl script(hello, randomized indentation!) dating back to 1998 that is still in production, and it shells out to nsgmls + Tcl for part of its SGML processing.

Perl, Tcl, and SGML. In 2014. Amazing!

Yes, @bkuhn is right; Perl is the new COBOL. What does that make Tcl?
