There doesn't appear to be a yum repository maintained for mono anymore.  I would like to help contribute a repository as my corporation supports mono applications and has a vested interest in ensuring mono is available to Fedora, RHEL, and CentOS systems.  I have requested assistance in obtaining mono RPM specs via the mono mailing lists, and my company would be willing to provide hosting, compute, and storage resources for building and packaging mono for the repository.  Per their recommendation, I am hoping to contribute this to EPEL and hope that you can provide guidance in creating the repository and maintaining the RPM spec files that I have, as yet, been unable to find.

What are the next steps to a) getting the RPM spec files to do mono packaging and b) creating a yum repository suitable for EPEL to serve the mono packages?

Best regards.
