However, I suspect that it is redundant given the rather significant body of build system documentation in the Wiki's Commentary.
Ultimately all of this build system documentation will hopefully be obsoleted with the removal of the make build system in favor of Hadrian. It's hard to know what to do in cases like this. There is likely still archival value in this documentation but as archival documentation accrues the signal-to-noise ratio of the entire body of documentation falls. I am hope that we can avoid this in the future by erring towards keeping documentation in the repository, where it is easier to ensure that documentation tracks changes in the implementation that it describes.
