Log Message:
py-daemon: updated to 2.2.3

Version 2.2.3

Bug Fixes:
* Use custom fake file type for testing fileno behaviour.

  This works around an incompatibility in Python 2.7 file type that
  caused test cases to fail.

  This has been an unofficial example module from the beginning, and
  it will be removed in a future version.

Version 2.2.2

Bug Fixes:
* Remove from the build system specification a white space character
  not permitted in TOML format.

Additions:
* Implement test suite automation in virtualenvs, using Tox.

Version 2.2.1

Additions:
* Add a :PEP:518 conformant build system specification (the
  pyproject.toml file).
