"""
[EXTRA FEATURE] Install external packages in a Spack upstream database using spood

Reads external packages from a YAML file, detect OS packages, installs them into Spack upstream database, and generates
`packages.yaml` entries (Spack needs to see compilers here).

Configure Spack user paths before running this script:
    export SPACK_USER_CONFIG_PATH=/home/lercole/eessi/spack
    export SPACK_USER_CACHE_PATH=/home/lercole/eessi/spack/cache
