error: unrecognized arguments: --learn about afew HOT 1 OPEN

Hey,
thank you for reporting this.

After checking the sources it is mostly gone for a while now,
some code is still in the project if you are interested.

afew 1.1.0 (2017-06-12)
=======================

Classification system removed

  As of commit 86d881d948c6ff00a6475dee97551ea092e526a1, the classification
  system (--learn) was removed, as it was really broken. If someone wants to
  implement it properly in the future it would be much simpler to start from
  scratch.

Also it seems that section of the doc is gone too, it's only showed in the stable version,
that something we need to cleanup for sure, but if you want you can check the latest until this page is refreshed.

from afew.
