This command line configuration example:

reads the UK federation metadata aggregate from its distribution site
verifies the aggregate's signature using the X.509 certificate taken from path/to/ukfederation-2014.pem
removes three specific entities belonging to the Shibboleth project
removes all entity role descriptors other than IDPSSODescriptor, SPSSODescriptor or AttributeAuthorityDescriptor
removes any person or organization contact information
writes the results into the file path/to/output.xml

You can execute the example as follows:

$ .../mda.sh config.xml main
