For a quick overview of Spack's features, we recommend this short presentation https://tgamblin.github.io/files/Gamblin-Spack-SC15-Talk.pdf
or the following videos from lead developers:
(1a) If you plan on using `GCC/Clang` as a compiler:
```
# Clone standard version of Spack
-git clone https://github.com/llnl/spack.git $WOODYHOME/spack
