commit e0ffc386e83a86089a54f50fc456bfb9a80c7db7
Author: Dan Walsh <dwalsh at redhat.com>
Date:   Wed Nov 16 15:41:18 2011 -0500

    Add listing of distribution equivalence class from semanage fcontext -l
    Add checking to semanage fcontext -a to guarantee a file specification will not be masked by an equivalence
    
    Allow ~ as a valid part of a filename in sepolgen
