- '''
- BitBake 'Fetch' implementations
- This implementation is for Secure Shell (SSH), and attempts to comply with the
- IETF secsh internet draft:
- http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
- Currently does not support the sftp parameters, as this uses scp
- Also does not support the 'fingerprint' connection parameter.
