Subject: [PATCH] add executable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new --executable option to distribute so that we can
force the shebang line in installed python scripts.

[Thomas: refresh for setuptools 5.8.]
[Jörg: refresh for setuptools 18.7.1]
