Michael Terry from the mail list:

Here's a second shot at adding machine-readable output to duplicity.  This
version depends on nothing more than the logging module in Python.  No glib or

It adds two new arguments (--log-fd and --log-file).  It writes to the fd or
file well-formed 'stanzas' as normal duplicity messages are output.

For example, if duplicity was going to put an error about command line
syntax, the log would show:

. Command line error: Expected 2 args, got 0\n
. Enter 'duplicity --help' for help screen.\n

The stanza starts with a keyword, has a message id number, followed by some
suggested user text and ending with a newline.  Currently, the 'named'
verbosity levels are all supported (DEBUG, INFO, NOTICE, WARNING, ERROR).

You can output to multiple files or fd at a time.  As part of this change, I
rewrote the current logging to use the logging module too. I've attached the
diff, the readme, and a small unit test file.

Like the first patch, I also made some additional small changes -- I made the
return value for --help be 0, and I added some message id numbers: ERROR 2 is
command line syntax error, 3 is source mismatch.  WARNING 2 -> 6 are certain
'unmatched files were found' warnings.
