Building Less?

[Warner Losh]

src.conf is only used to build /usr/src. src.con(5) documents that. build(5) has a pointer.

How would you suggest making this clearer?

If the srcconf option is not described on man page for the build process, then it's existence would not be known to someone reading about building (i.e. me). More to the point, if I had come across the file myself, I would have wondered if it was even relevant to this version of the OS as it is not referenced in the only spot it is used (hence my question). I have experienced this confusion in the documentation before.
