Is the GHC release process documented?

Friends, While writing a new nofib benchmark today I found myself wondering whether all the nofib benchmarks are run just before each release, which the drove me to go look for a document describing the release process. A quick search didn't turn up anything, so I thought I'd ask instead. Is there a documented GHC release process? Does it include running nofib? If not, may I propose that we do so before each release and compare the result to the previous release*. * This likely means that nofib has to be run for the upcoming release and the prior release each time a release is made, as numbers don't translate well between machines so storing the results somewhere is likely not that useful. Cheers, Johan
