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
* Add package for nginx@1.12.0
Includes support for:
- zlib
- pcre (and pcre-jit)
- openssl (https support)
Built and basics tested on CentOS 7. I haven't tested the `https`
support [yet].
* Include final bit of doc string sentence.
I trimmed the docstring that I lifed from https://nginx.org/en a bit
too aggressively and left a '...' to remind me to fix it.
Apparently I need more obvious reminders.
Thanks @davydden!
