5BitBake 'Fetch' implementations
6
7This implementation is for Secure Shell (SSH), and attempts to comply with the
8IETF secsh internet draft:
9 http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
10
11 Currently does not support the sftp parameters, as this uses scp
12 Also does not support the 'fingerprint' connection parameter.
