EPEL Specific Packaging Guidelines
This page contains guidelines which are no longer relevant to Fedora, but still apply to EPEL packages (EL-4 and/or EL-5). These guidelines are designed to avoid conflict with the larger Fedora Packaging Guidelines, but should any conflicts occur, these guidelines should take precedence (on EPEL packages).
As a reminder, these guidelines only apply to EPEL packages, not to Fedora packages.
