># packages based on a repository priority.
>#
># You can install this plugin by copying it to /usr/lib/yum-plugins. To
># enable this plugin, make sure that you have 'plugins=1' in /etc/yum.conf,
># and create the file /etc/yum/pluginconf.d/priorities.conf with the
># following content:
>#
># [main]
># enabled=1
>#
># If you also want the plugin to protect high-priority repositories against
># obsoletes in low-priority repositories, enable the 'check_obsoletes' bool:
>#
># check_obsoletes=1
>#
># You can add priorities to repositories, by adding the line:
>#
># priority=N
>#
># to the repository entry, where N is an integer number. The default
># priority for repositories is 99. The repositories with the lowest
># number have the highest priority.
