The idea was to place the code to provide that information into the
applications pkg_getinfo() section, nothing major, just version
numbers etc, and possibly code to test for scenarios that are known to
exist but theres currently no known way to fix them.

Some of these basic checks can be as simple as grabbing the files
CONTENTS out of edb, and checking all the files listed in it exist,
and are of the right type ( cat CONTENTS | tr "\n" "\0" | xargs -iSTR
-0 file STR ), and arn't symlinks that don't go anywhere, you know,
the usual sort of bugs that flare up as a result of user interaction
;))

The output of those checks are still going to be want to be read and
interpreted by a human, but the more you know of a situation, the more
you have to find the bug with.
