package require BLT
# --------------------------------------------------------------------------
# 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
#
