Aggregate and Sign

This command line configuration example:

reads a directory of files at path/to/input/entities/ containing SAML metadata files representing individual entities
removes any person or organization contact information
wraps the results in an EntitiesDescriptor
signs the document using a private key taken from the file path/to/input/private-key.pem
writes the results into the file path/to/output/signed-aggregate.xml

You can execute the example as follows:

$ .../mda.sh aggregate-and-sign.xml main
