In python\n   memory block is represented as a buffer-like object.\n3. ring: lockless FIFO queue in share memory. user can use `Ring` to manage the\n   memory blocks allocated from Mempool\n\n## installation and usage\n\nyou can install pyshm using setuptools or pip:\n\n    pip install pyshm\n\nor:\n\n    python setup.py install\n\n## usage\n\n1. create share memory\n\n        from pyshm import ShareMem\n\n        test_shm = ShareMem(64*1024*1024) # 64M\n\npls note: these code should execute before `fork`\n\n2. using mempool\n\n        from pyshm import mempool\n        count = 4\n        mp = mempool.Mempool(count, 4, shm=test_shm)\n\n        pid = os.fork()\n        if pid == 0:\n            for i in range(count):\n                buf = mp.get()\n                struct.pack_into(\"=i\", buf, 0, i)\n                mp.put(buf)\n        else:\n            cid, status = os.wait()\n            assert pid == cid\n            for i in range(count):\n                buf = mp.get()\n                v, = struct.unpack_from(\"=i\", buf)\n                assert v == i\n            mp.cleanup()\n\n`get` used to get memory block(a buffer-like object), `put` returns the memory block to the mempool\n\n3. using ring\n\nring can used to pass the memory block(get from mempool) to the other process.\nit proviod `enqueue` and `dequeue`, one process enequeue and the other process `dequeue`",
