We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
* Added a package for the MDAnalysis toolkit.
* Added a new package for pygpu, which is the python front end of the
libgpuarray. Additionally changed the dependency for theano so that
it properly picks up the pygpu library.
* Added the libcheck package. Fixed flake8 errors in py-pygpu recipe
and removed spurious dependency on cudnn for libgpuarray.
* Added support for building Theano with GPU support. Added a package
for the libgpuarry libary needed for Theano.
* Added dependency on py-pexpect package which ipython requires.
