2015-04-02	Switch PkgVersion to use composition	Jack Nagel
	Comparing PkgVersion and Version objects can produce nonsensical results. For example, equality is not symmetric: irb(main):002:0> PkgVersion.new("1.0", 0) == Version.new("1.0") => false irb(main):003:0> Version.new("1.0") == PkgVersion.new("1.0", 0) => true Rather than attempt to deal with subclass-superclass equality, let's use composition and punt on the problem altogether.

2014-03-05	Encode formula revision in installation prefix	Jack Nagel
	In order to allow kegs built with the same version but differing formula revisions to coexist, we must encode the revision as part of the keg's name. This is necessary to actually perform an upgrade, as we cannot upgrade a keg in-place, and temporarily moving it pending the result of the upgrade is error-prone and potentially slow. To accomplish this, we introduce a new Formula#pkg_version method that concatenates the active_spec version with the formula revision. An exception is made for a formula that has no revision: the tag is omitted. This preserves compatibility with existing installations.
