+ Docstring warnings fixed.
 + Multiline param descriptions indented by 4 spaces.
 - Except the PacketVerifier.py one
  - I have tried several quote-like blocks, nothing works.
- Rst warnings not fixed.
 - How can I fix them? They refer to temporarily created files.
+ Other improvements:
 + Python lines no longer than 80 characters.
 + :return: -> :returns:
 + Notes before params.
 + :raises
  + closing colon after exception class.
  + Description is a sentence.
  + Present tense in conditional sentences.
+ Bumped copyright year in edited files.
