sysutils/node_exporter: Add tests, docs and examples - Define LICENSE_FILE. - Sort variables. - Add a do-test target and prepare a testing environment. One test is skipped at the moment due to a problem with detecting procfs(5) on FreeBSD. - Install documentation and examples. - Change pkg-descr to better match upstream's README.
I am not sure about a couple of things, however:
- Is it fine to use USES=gmake instead of TEST_DEPENDS=gmake:devel/gmake? USES=gmake adds a dependency to the build process, which is not ideal.
- The whole pre-test target is rather hacky. I was unable to come up with a prettier solution though. Go is a little bit hard to tame.
