# You can either use Metrowerks-supplied scripts (e.g. "<CodeWarrior>/Other
# Metrowerks Tools/Command Line Tools/cwenv.bat") to set up the appropriate
# environment, set up environment variables by hand as described in
# "<CodeWarrior>/Release Notes/CLT Notes/CLT_Usage_Notes.txt", or you can define
# METROWERKS_ROOT to be the metrowerks installation directory, and cwenv.bat
# will be invoked before each tool invocation.

# We go this route because the environment needed to run the metrowerks tools
# from the command-line is sufficiently complex to make using the borland
