Presto: A project to add delta rpm support into yum for Fedora users
https://hosted.fedoraproject.org/projects/presto/wiki/WikiStart
Most of the code base has been written by Marcel Hild <mhild@redhat.com> as up2date/satellite-server delta rpm support. Code adaptation for yum done by Ahmed Kamal <email.ahmedkamal@googlemail.com>

Installation:
=============
1- Make sure deltarpm is installed on your system (yum -y install deltarpm)
2- Place the files in the following locations (/usr/share/deltarpm-python/deltarpm.py /usr/lib/yum-plugins/yum-deltarpm.py /etc/yum/pluginconf.d/yum-deltarpm.conf)
3- Modify the conf file to point to any test repo you have setup
4- Use the server.py script to generate drpms from different update levels of some rpms in your test repo
5- Now install an old rpm from your repo using rpm, try updating it using yum. The plugin should kickin, try to download the drpm, reconstruct the full rpm, and yum should install that

Notes:
=====
- The code is in a *very* early stage. Minimal testing has been done.
- I (Ahmed) will probably be helping/maintaining this project, but probably I will not be the lead developer behind this
