* cp2k: prettify arch-file, call pkg-config directly this allows to re-use the arch-file without having to load the complete Spack environment, for example after a dev-build * cp2k: use consistency check instead of blas lib enum this makes using other BLAS/LAPACK implementations possible without explicitly adding support for them * cp2k: add basic support for Cray and XL Compilers, correct Intel fp mode * cp2k: add myself as maintainer * cp2k: use "master" to denote the git version * cp2k: use spack_cc/fc/cxx when possible, set CXX explicitly * cp2k: set __MKL when using the MKL, not just the Intel compiler * cp2k: drop self. when referencing spec where possible * cp2k: add forgotten elpa+openmp dep * cp2k: set C++14 for recent versions |

Spack
Spack is a multi-platform package manager that builds and installs multiple versions and configurations of software. It works on Linux, macOS, and many supercomputers. Spack is non-destructive: installing a new version of a package does not break existing installations, so many configurations of the same package can coexist.
Spack offers a simple "spec" syntax that allows users to specify versions and configuration options. Package files are written in pure Python, and specs allow package authors to write a single script for many different builds of the same package. With Spack, you can build your software all the ways you want to.
See the Feature Overview for examples and highlights.
To install spack and your first package, make sure you have Python. Then:
$ git clone https://github.com/spack/spack.git
$ cd spack/bin
$ ./spack install zlib
Documentation
Full documentation is available, or
run spack help or spack help --all.
Tutorial
We maintain a hands-on tutorial. It covers basic to advanced usage, packaging, developer features, and large HPC deployments. You can do all of the exercises on your own laptop using a Docker container.
Feel free to use these materials to teach users at your organization about Spack.
Community
Spack is an open source project. Questions, discussion, and contributions are welcome. Contributions can be anything from new packages to bugfixes, documentation, or even new core features.

Contributing
Contributing to Spack is relatively easy. Just send us a
pull request.
When you send your request, make develop the destination branch on the
Spack repository.
Your PR must pass Spack's unit tests and documentation tests, and must be PEP 8 compliant. We enforce these guidelines with Travis CI. To run these tests locally, and for helpful tips on git, see our Contribution Guide.
Spack uses a rough approximation of the
Git Flow
branching model. The develop branch contains the latest
contributions, and master is always tagged and points to the latest
stable release.
