- 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 scalpel@0.5.3
Scalpel's a bit of a mess, it expects it's users to just unpack the
tarball, build it in the resulting directory and install that
directory onto their PATH. My install step recapitulates this into
prefix.bin. The alternative was rewiring their scripts (perl), which
use `FindBin` and expect things to be located in the same dir that the
script itself is.
Sigh.
Lightly tested on CentOS 7.
