If an outdated Xcode is installed, it really needs to be updated if
possible. Otherwise things that depend on Xcode at build time will have
that dependency satisfied, but will fail to compile. The CLT is enough
if it is installed by itself, in which case Xcode dependencies will not
be satisfied.

and flags accordingly.

Used to capture options that are being renamed.

Stop dumping files in the real HOME and allow Jenkins to handle
workspace cleanup instead.

Formulae should not require knowledge of Homebrew's internal directory
structure, and we should be able to alter it without modifying
individual formulae.

Massive TODO.

We'll get there eventually...
