-# --------------------------------------------------------------------------
-# Starting with Tcl 8.x, the BLT commands are stored in their own
-# namespace called "blt". The idea is to prevent name clashes with
-# Tcl commands and variables from other packages, such as a "table"
-# command in two different packages.
-#
-# You can access the BLT commands in a couple of ways. You can prefix
-# all the BLT commands with the namespace qualifier "blt::"
-#
-# blt::graph .g
-# blt::table . .g -resize both
-#
-# or you can import all the command into the global namespace.
-#
-# namespace import blt::*
-# graph .g
-# table . .g -resize both
