Homebrew 0.9

Homebrew 0.8.1

This version number is arbitrary, and only used to differentiate versions
in bug reports.

There have been enough changes to compiler detection since 0.8 that it makes
sense to bump the version here.

Homebrew 0.8

Bump Homebrew to 0.7.1

The Homebrew version number is mainly useful for bug reports. Since it is
included in "brew --config" output, it is an easy way to see roughly how
new the a user's version of Homebrew is.

Bumping the micro version now, in anticipation of some more version-changing
events in the near future.

Homebrew now at version 0.7

Changes in this version include:
* Aliases are now defined by relative symlinks rather than in the
  formulae themselves. Many commands are faster now that they don't
  have to read every formula to find aliases.

* "url" now supports the same features as "head", including ":using"
  and version specifiers for VCS systems.

* Files and methods marked for deprecation in 0.7 have been removed.

* The Formula DSL now supports "skip_clean :all" and "keg_only 'reason'"

Homebrew is now at version 0.6

We've bumped the version number, as Homebrew no longer tries to use LLVM
by default (on Snow Leopard.)

It's about time we bumped the version eh?

Refactor

Large refactor to Formula, mostly improving reliability and error handling but
also layout and readability.

General improvements so testing can be more complete.

Patches are automatically downloaded and applied for Formula that return a
list of urls from Formula::patches.

Split out the brew command logic to facilitate testing.

Facility from Adam Vandenberg to allow selective cleaning of files, added
because Python doesn't work when stripped.

Refactor--object orientate where sensible

Bump VERSION to 0.2
