- Spec comparison is now less strict
- compares based on sorted list of dependencies but not
their structure
- Makes comparison easy when a spec is not normalized.
- This makes the dep_hash consistent for specs read in from a
directory layout. - Can now reliably read in a spec for which the
package has gone away, and still be able to delete its install.
- easy switching between git branches
- Fixed latent bug in Spec.flat_dependencies() (was including root)
- added a test for the directory layout so that this code will get
more exercise.
