Log message:
py-portend: updated to 2.2

2.2
Merge with skeleton, including embedded license file.

Log message:
2.1.2
Fix README rendering.

2.1.1
Restored use of ``portend.client_host`` during
    ``assert_free`` check on Windows, fixing check
    when the bind address is *ADDR_ANY.

2.1
Use tempora.timing.Timer from tempora 1.8, replacing
boilerplate code in occupied and free functions.

2.0
Removed ``portend._getaddrinfo`` and its usage in
    ``Checker.assert_free``.

Dropped support for Python 2.6.

Log message:
Needs py-setuptools_scm.

Log message:
Added net/py-portend version 1.8:

Use portend to monitor TCP ports for bound or unbound states.

For example, to wait for a port to be occupied, timing out after 3 seconds::

	portend.occupied('www.pkgsrc.org', 80, timeout=3)

Or to wait for a port to be free, timing out after 5 seconds::

	portend.free('::1', 80, timeout=5)

The portend may also be executed directly. If the function succeeds, it
returns nothing and exits with a status of 0. If it fails, it prints a
message and exits with a status of 1. For example::

	python -m portend localhost:31923 free
	(exits immediately)

	python -m portend -t 1 localhost:31923 occupied
	(one second passes)
	Port 31923 not bound on localhost.
