4BitBake 'Fetch' implementations
5
6This implementation is for Secure Shell (SSH), and attempts to comply with the
7IETF secsh internet draft:
8 http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
9
10 Currently does not support the sftp parameters, as this uses scp
11 Also does not support the 'fingerprint' connection parameter.
