* @title: GcrImporter
* @short_description: Import certificates and keys
*
* An interface which allows importing of certificates and keys. Each
* #GcrImporter is registered with a set of PKCS\#11 attributes to match
* stuff that it can import.
*
* An importer gets passed a #GcrParser and accesses the currently parsed
* item. To create a set of importers that can import the currently parsed
* item in a #GcrParser, use gcr_importer_create_for_parsed(). The list of
* importers returned has the parsed item queued for import.
*
* To queue additional items with a importer use gcr_importer_queue_for_parsed().
* In addition you can try and queue an additional item with a set of importers
* using the gcr_importer_queue_and_filter_for_parsed().
*
* To start the import use gcr_importer_import() or the async variants.
