Description:

When rpmfind is asked for a resource it first asks the local RPM base,
and if it's not available, will request the associated RDF file on
a remote database. The result describes the various packages
providing these resources (distribution, vendor, version, date, etc...).

Based on that information, rpmfind sorts the various packages for
suitability.
Then it picks the first one and fetchs more complete information like
the dependencies required by this package. It then verifies that all
the dependencies needed by this package are available, and recusively
trys to locate RPM providing uninstalled resources.

At the end rpmfind shows the list of packages to fetch and the total
size needed on disk.

The database can be built using rpm2html.
