can you describe what is a value in this dictionary?

Done.

perhaps rename value -> entries to be more consistent with the
VerifyRegistryEntries signature.

[sukolsak, 2013/08/12 19:20:20]

Other verifiers that I am going to add will have different signatures.

     if verifier_name == 'RegistryEntries':
       registry_verifier.VerifyRegistryEntries(value)
     else:
       # TODO(sukolsak): Implement other verifiers
-      # TODO(sukolsak): Use unittest framework instead of exceptions.
