title: lcontain in tcl 8.5.9
body: <p>I'm running a program using Tcl 8.5.9, specificly: <code>/tcl/8.5.9_64/bin/wish8.5</code> I'm trying to use the <code>lcontain</code> command, but the tcl doesn't recognize it. Was it excluded from that version? and is there a different command to replace it?</p>
