# This is a the master build script - it is intended to be run by the Linden
# Lab build farm
# It is called by a wrapper script in the shared repository which sets up
# the environment from the various BuildParams files and does all the build 
# result post-processing.
#
# PLEASE NOTE:
#
# * This script is interpreted on three platforms, including windows and cygwin
#   Cygwin can be tricky....
# * The special style in which python is invoked is intentional to permit
#   use of a native python install on windows - which requires paths in DOS form
# * This script relies heavily on parameters defined in BuildParams
