rose-build.sh

#!/usr/bin/env bash
#
# Detects options and path settings and runs configure and make.
# 
# Usage:
# rose-build.sh -r <src-path> -p <install-path>:
# - src-path: unpacked ROSE source directory
# - install-path: installation path (should be an absolute path)
#
# After options are determined, each of the following commands can be selected.
# - configure
# - make
# - make install

#set -u
