This directory should contain configuration files used for loading federations
in authentic2. These files should be Bash scripts (they must bear a '.sh'
extension), and they should declare two variables:

- METADATA: the XML metadata file.
- SOURCE: a keyword entry (e.g. 'renater, 'edugain') for authentic2 to handle
  this federation.

Sample files are located at
/usr/share/doc/authentic2-supann/federations.d-examples
