Let an environment variable, HOMEBREW_MAKE_JOBS, override the default
'-j<cores>' make flag.
Now we can more easily debug formula that normally build in parallel, or
(potentially) speed up lengthy builds.
This is needed for Ruby 1.9.x compatibility, but we still don't support
running Homebrew with anything other than a system provided 1.8.[67].

Before we would always make the symlink itself have a basename the same as what it pointed to.
I don’t think this breaks any of the other usages as they were working by coincidence.
SourceForge links can end with /download which appears to be part of
what is used to drive mirror selection. Modifying the version detection
extension of pathname.rb to detect this case for both sourceforge.net
and sf.net download selections.
This is sufficient for version detection but may not be sufficient for
other uses of /download links. I have not found any problems with links
that use /download, though.

Be more useful by being more concise. I referenced dozens of other mature commands’ usage to figure out what to do here.
Also separated out the help into its own command for consistency.
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.
