* Add +cfitsio variant to wcslib dependency

* Replace ncurses dependency with readline dependency

casacore explicitly may depend on readline, not ncurses

* Add workaround for casacore's readline dependency

casacore optionally depends upon readline, but it's CMakeLists.txt provides no
user control over whether or not readline becomes a dependency. As readline is
often present by default on systems, it's better for this package to explicitly
depend on readline in order to prevent linking to whatever system version of the
library happens to be found during the build process. This should be considered
a workaround until casacore's CMakeLists.txt is fixed.

* Apply workaround for casacore's dependency on SOFA

Similar to the issues with casacore's readline dependency, casacore's optional
dependency on SOFA does not provide the user with a means of controlling the
dependency during build time. Unlike the readline library, the SOFA library is
unlikely to exist on most systems by default. As the SOFA dependency is only
optionally used for testing casacore, requiring it by default is not a good
workaround. Until casacore's CMakeLists.txt is fixed, this variant has been
removed to avoid unexpected library dependencies in the installed package.

* Add newer casacore versions

* Add mpokorny to maintainer field

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.

Resources:

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.
