# directory to some other location, placing all binaries, libraries, and
# docs in their final locations relative to each other.

# It requires the following variables to be set:
#
# PREPARE_HOST - the host triple
# PREPARE_TARGETS - the target triples, space separated
# PREPARE_DEST_DIR - the directory to put the image
