#
# - This script is what most developers use to build/rebuild this package.
# - This script works for both CMake and distutils based packages.
# - If this script is updated in one package, please propagate to the others!
#
# Environment variables:
#
# - $PROCS : controls number of processes to use for build
# : defaults to 6
# - $FENICS_PYTHON_EXECUTABLE : name of python executable
# : defaults to "python"
# - $FENICS_INSTALL_PREFIX : path to FEniCS installation prefix
# : defaults to "${HOME}/opt/<branchname>"
# Exit on first error
