# This module extends the stock distutils install_setup code to
# support installation into multiple target directories, with
# semantics similar to what distutils already supports for
# script_files. The bulk of this code is taken directly from the
# stock distutils package, with minor changes. As such, I consider
# this to be a derivative work of the distutils package for copyright
# purposes.
