progress output

[abuisine]

rather than a complete verbose output, it would be interesting to have some kind of progress indication, preferably parseable :)

You can do it with stdout and stderr, for the rest you have to write it alone, if you want to see an example of an output you can view here. https://www.patreon.com/guetzli

Thinking about it, I feel there should be a kind of human readable (simplified) output. Creating wrappers is doable, but given the length of a guetzli process it should be included in the soft. That was my 2 cents :)

A nice parsable JSON output would be great....
