[swift-users] WARNING: Title underline too short

Wed Dec 23 13:30:06 CST 2015

Snapshots and HEAD should always build cleanly on all supported platforms, so we ought to fix this. It may be that our buildbots don't have sphinx installed, so the docs aren't getting checked there. Disabling sphinx in your build config should work around it in the meantime.

I cannot find a reference to "WARNING: Title underline too short" (which might be the failing error?  although the output continues for quite some time) on this list or on bugs.swift.org <http://bugs.swift.org/>, but presumably somebody has tried to build Swift at some point in the past few days
