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
