#
# This script links an HPCToolkit satellite repository (this
# directory) with a main spack repository.
#
# The main spack repo contains the build scripts and config files for
# building a few thousand packages with spack.  This, the satellite
# repo contains the config files for building the HPCToolkit
# prerequisite packages with options needed for HPCToolkit.
#
# This script links the satellite repo to the main spack repo by
# creating two files in the spack repository in the directory:
# <spack-root>/etc/spack:
#
#  config.yaml -- sets install_tree to the root of the install prefix
#        for the hpctoolkit packages.
#
#  repos.yaml -- sets the location of the satellite repository.
#
# This script also creates the file 'env.sh' in this directory.
# Source this file to put the spack bin directory on your path.
#
# Usage:  ./setup.sh  spack-root  [prefix]
#
#  spack-root = path to the main spack repository
#  prefix = path to the install prefix (optional)
