http://presto.fedorahosted.org.  A list of presto-enabled repositories is
available there.

presto-utils: Tools for working on presto repositories

Installation:
=============
1- Untar the package
2- Run 'python setup install'

To create a presto repository:
1- First run 'createdeltarpms <repo dir> <drpm dir>' where <repo dir> is the
   base directory for your repository and <drpm dir> is the subdirectory you
   want to create the deltarpms into
2- Run 'createprestorepo <deltadir> <outputdir>' where <deltadir> is the base 
   directory for your repository that contains the deltarpms and <outputdir> is
   the location you want prestodelta.xml saved.
3- Run 'modifyrepo <outputdir>/prestodelta.xml <repodir>' where <outputdir> is
   the <outputdir> specified in step 2 and <repodir> is the repodata directory
   for your repository generated by createrepo.

To remove old deltarpms:
1- First remove old rpms from your repository using the tools available in
   yum-utils
2- Run 'prunedrpms <repo dir>' where <repo dir> is the base directory for your
   repository.
