-/** \ingroup python
- * \class Rpmdb
- * \brief A python rpmdb object represents an RPM database.
- *
- * Instances of the rpmdb object provide access to the records of a
- * RPM database. The records are accessed by index number. To
- * retrieve the header data in the RPM database, the rpmdb object is
- * subscripted as you would access members of a list.
- *
- * The rpmdb class contains the following methods:
- *
- * - firstkey() Returns the index of the first record in the database.
- * @deprecated Use mi = ts.dbMatch() (or db.match()) instead.
- *
- * - nextkey(index) Returns the index of the next record after "index" in the
- * database.
- * @param index current rpmdb location
- * @deprecated Use hdr = mi.next() instead.
- *
- * - findbyfile(file) Returns a list of the indexes to records that own file
- * "file".
- * @param file absolute path to file
- * @deprecated Use mi = ts.dbMatch('basename') instead.
- *
- * - findbyname(name) Returns a list of the indexes to records for packages
- * named "name".
- * @param name package name
- * @deprecated Use mi = ts.dbMatch('name') instead.
- *
- * - findbyprovides(dep) Returns a list of the indexes to records for packages
- * that provide "dep".
- * @param dep provided dependency string
- * @deprecated Use mi = ts.dbMmatch('providename') instead.
- *
- * To obtain a db object explicitly, the opendb function in the rpm module
- * can be called. The opendb function takes two optional arguments.
- * The first optional argument is a boolean flag that specifies if the
- * database is to be opened for read/write access or read-only access.
- * The second argument specifies an alternate root directory for RPM
- * to use.
- *
- * Note that in most cases, one is interested in querying the default
- * database in /var/lib/rpm and an rpm.mi match iterator derived from
- * an implicit open of the database from an rpm.ts transaction set object:
- * \code
- * import rpm
- * ts = rpm.TransactionSet()
- * mi = ts.dbMatch()
- * ...
- * \endcode
- * is simpler than explicitly opening a database object:
- * \code
- * import rpm
- * db = rpm.opendb()
- * mi = db.match()
- * \endcode
- *
- * An example of opening a database and retrieving the first header in
- * the database, then printing the name of the package that the header
- * represents:
- * \code
- * import rpm
- * db = rpm.opendb()
- * mi = db.match()
- * if mi:
- * h = mi.next()
- * if h:
- * print h['name']
- * \endcode
- *
- * To print all of the packages in the database that match a package
- * name, the code will look like this:
- * \code
- * import rpm
- * db = rpm.opendb()
- * mi = db.match('name', "foo")
- * while mi:
- * h = mi.next()
- * if not h:
- * break
- * print "%s-%s-%s" % (h['name'], h['version'], h['release'])
- * \endcode
