# genlib.tcl
#
# generate the Lib directory with the needed components for slicer
# to build
#
# Steps:
# - pull code from anonymous cvs
# - configure (or cmake) with needed options
# - build for this platform
#
# Packages: cmake, tcl, itcl, iwidgets, blt, ITK, VTK, teem
# 
# Usage:
#   genlib [options] [target]
#
# run genlib from the Slicer3 directory next to where you want the packages to be built
# E.g. if you run /home/pieper/Slicer3/Scripts/genlib.tcl it will create
# /home/pieper/Slicer3-lib
