 The .yaml files in the .spack/linux directory contains information which tolls you want to include from the UPPMAX system.
 
 - The compilers.yaml file lists the compilers (intel or gcc) modules available to build your software tool.
 - The packages.yaml file lists tools available already as modules.
 
-By default, these files are empty but you can copy working "central" files that can be extended for your needs. The content of the files can be larger than the needed packages/compilers, i.e. only the packages /dependencies needed for your installation will be "taken" from these files and the rest will be ignored. Therefore, the UPPMAX staff may update these central files once in a while.
