Per-entity Output

This command line configuration example:

reads a file path/to/input/aggregate.xml containing a SAML metadata aggregate
decomposes that aggregate into its constituent entity metadata documents
signs each of those per-entity documents using a private key located in path/to/secrets/private-key.pem
writes the results into multiple files in the directory path/to/output. Each file is named as a function of the entity's entityID attribute:
- the string "_", followed by
- a lower-case, hex-encoded, SHA-1 hash of the entityID, followed by
- the string ".xml"

You can execute the example as follows:

$ .../mda.sh per-entity.xml main
