- 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
* Fix mummerplot when ^perl@5.20:
Calling defined() on a hash has been deprecated for ages. It became
an error in perl@5.20. If we're building with a perl where it's
illegal, we should fix it.
* Simplify call to filter_file
Treat the first arg to filter_file as a string rather than
a regex, so that we don't have to figure out the escapes.
* Patch mummerplot for *any* perl version.
* Trailing whitespace cleanup
* Handcraft an install process for mummer (grumble)
Mummer punts on an installation step, they just build in and run from
the same directory.
Mummer also has various hardcoded paths built into it that allow it to
find other executables that it needs as well as its Perl library.
This updates the package to deal with this approach.
It patches the Makefile and scripts/Makefile so that the correct info
is fed to sed when it munges the perl scripts.
The install step is now finer grained and puts things where mummer
relatively wants to find them.
* Add perl dependency
* perl should be build/run dependency
* Fix whitespace
* Delete stray u at top of file
