/** \ingroup python
* \class Rpmii
* \brief A python rpm.ii key iterator object represents the keys of a
* database index.
*
* The rpm.ii class conains the following methods:
* - next() -> key Return the next key.
*
* To obtain a rpm.ii object to query the database used by a transaction,
* the ts.dbIndex(tag) method is used.
*
* Here's an example that prints the name of all installed packages:
* \code
* import rpm
* ts = rpm.TransactionSet()
* for name in ts.dbIndex("conflictname"):
* print name
* \endcode
*
* ts.dbIndex() can be used to get the packages containing the keys of interest
