=over
=item new
Creates a tied hash using a lexically-scoped hash table, then returns a
reference to it (the return value of the C<tie> operation). This reference
prevents the hash table from going out of scope. If a hash-reference of
options is passed to this constructor, they are passed along to the tie of the
hash. If a single scalar argument is passed, it is assumed to be an alternate
database root to be used in opening the RPM database. The hash-reference
currently only supports a single key, C<root>, which serves the same
purpose. The hash-reference approach leaves open the possibilty of future
options being added.
=item init
This causes a complete initialization of the RPM database. It must be run
