Provided the user installed with our installer anyway. It creates all the directories that Homebrew will need during its life thus negating the need for root writability.
Currently, `brew doctor` complains about GREP_OPTIONS being set,
regardless of its value. The cmake formula, for which this check was
introduced, is more specific about what actually makes it fail.
GREP_OPTIONS='--color=auto' will not cause the build to fail, so don't
warn about this.

XCode 4.x only includes GCC 4.2. Therefore, having `brew doctor` report that
GCC 4.0 is missing only spreads fear, uncertainty and doubt over a situation
that is status quo.

The HOMEBREW_(LLVM|GCC) variables mentioned in brew-doctor's
`check_cc_symlink` method are actually named HOMEBREW_USE_(LLVM|GCC)

This allows you to use llvm as your default compiler and keep the cc symlink
pointed at llvm, while allowing you to build forumla that requires the gcc.

The code was sucking. To the extent that maintenance was hard. It's a lot
easier to work with code that is sensibly split at sensible boundaries. So
now it is more like that.
But the refactor is minimal. Because we don't want you to have more merge
hell than absolutely necessary.
If you merge you will need to pay attention to brew.h.rb (as it is deleted)
and bin/brew (as command logic is gone). It will be painful, but you will just
have to help git out by moving any changes around manually.
Note compatibility.rb. It ensures that any function renames or removals don't
break anything. We're pretty serious about backwards compatibility. And that's
because we encourage you to hack around with the innards. And we couldn't do
that if we would then just make stuff disappear behind your back.
