VNF or PNF CSAR Package
------------------------

CSAR Overview
^^^^^^^^^^^^^

TOSCA YAML CSAR file is an archive file using the ZIP file format whose
structure complies with the TOSCA Simple Profile YAML v1.2 Specification.
The CSAR file may have one of the two following structures:

  - CSAR containing a TOSCA-Metadata directory, which includes the TOSCA.meta
    metadata file providing an entry information for processing a CSAR file.

  - CSAR containing a single yaml (.yml or .yaml) file at the root of the
    archive. The yaml file is a TOSCA definition template that contains a
    metadata section with template_name and template_version metadata. This
    file is the CSAR Entry-Definitions file.
