+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.
