Hi, Greg! Library author here. I'd be happy to add a configurable UserAgent. Perhaps the default would be a generic "waybackpack" but could be configurable to add contact info for the user. Does that sound about right? Prefer a different approach?
And, yep, the library is intentionally designed only to request one snapshot at a time.
waybackpack would be a great default; encouraging the actual user to add contact info would be better for you because we could complain to them instead of you :-)
