- '''
- 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.
- Please note that '/' is used as host, path separator not ':' as you may
- be used to, also '~' can be used to specify user HOME, but again after '/'
-
- Example SRC_URI:
- SRC_URI = "ssh://user@host.example.com/dir/path/file.txt"
- SRC_URI = "ssh://user@host.example.com/~/file.txt"
