* brew install will find an aliased formula
* aliases are searched against
* warn when creating a new formula that has an existing alias.
If Subversion has an alias "svn", then warn when the user tries to
create a new formula "svn". The formula can still be created, though
the user should make sure it's not a duplicate of the existing
aliased one.
Subversion and Objective-Caml formulas get some alises here, so we have
something to test against.
The "fixes" to this formula for 10.6 completely broke it on 10.5.
The formula now has separate setup / deps handling for 10.5 and
10.6, which should work until Subversion 1.7 comes out some day
and the Snow Leopard system deps break again.
brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.

As I understand it, this is not required on 10.6. But then again this formula
isn't really required on 10.6.
Is it a DSL? No. But people call it that apparently.
To add a dependency:
class Doe <Formula
depends_on 'ray'
depends_on 'mee' => :optional
depends_on 'far' => :recommended
depends_on Sew.new
end
Sew would be a formula you have defined in this Formula file. This is useful,
eg. see Python's formula. Formula specified in this fashion cannot be linked
into the HOMEBREW_PREFIX, they are considered private libraries. This allows
you to create custom installations that are very specific to your formula.
More features to come, like specifying versions
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.
