# == Synopsis
#
# Remove package files from a build folder.
#
# The list of files to remove are taken from a source package directory
# (typically a folder under an svn working copy) 
# (see list_package_files.rb script)
#
# == Usage
#
# remove_package_files_from_buid_tree [OPTIONS] PACKAGE_SUBDIR BUILD_ROOT
#
# PACKAGE_SUBDIR  the source package sub directory used to generate the file list
#
# BUILD_ROOT  the destination build root directory where the files will be removed
#
# OPTIONS:
#
# -h, --help:
#    show help
#
# -r, -rename
#    Rename files instead, adding a ".removed" suffix
#
