From 8404c0cd50291445fb57736bb3314bd0d75bebba Mon Sep 17 00:00:00 2001 From: "Darryl L. Pierce" Date: Tue, 12 Mar 2013 13:21:20 +0000 Subject: QPID-4115: Moved the Python send and receive apps. Instead of being API examples, they are actually tools that belong with the other tool apps. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk@1455522 13f79535-47bb-0310-9956-ffa450edef68 --- qpid/python/examples/api/receive | 194 --------------------------- qpid/python/examples/api/send | 281 --------------------------------------- 2 files changed, 475 deletions(-) delete mode 100755 qpid/python/examples/api/receive delete mode 100755 qpid/python/examples/api/send (limited to 'qpid/python/examples/api') diff --git a/qpid/python/examples/api/receive b/qpid/python/examples/api/receive deleted file mode 100755 index f14df277ac..0000000000 --- a/qpid/python/examples/api/receive +++ /dev/null @@ -1,194 +0,0 @@ -#!/usr/bin/env python -# -# Licensed to the Apache Software Foundation (ASF) under one -# or more contributor license agreements.
