Just an update, I've tried to bring the tests over today, but they're 
quite dependent on the implementation.

I still have 6/10 failures, so far.

One thing I've noticed that you omitted is the inclusion of the 
"commentary" field in the package-desc struct.

Not sure what the justification for its inclusion was, but I've had to 
remove the related assertions from the test file.

Daniel:

One thing I definitely didn't like is the usage of raw cl-struct vectors 
as reference values to compare against. These are implementation details 
of cl-defstruct, and we have no business setting them in stone in a test 
suite for code that just uses defstruct.

Relying on an external program (ginstall-info) is also not nice, for the 
usual alternative-OS-related reasons.
