// TODO: Handle error\n \n return YES;\n}\n\n```\n\nAnd here's an example session:\n```sh\n$ telnet localhost 2323\nTrying 127.0.0.1...\nConnected to localhost.\nEscape character is '^]'.\nYou are connected from 127.0.0.1 using \"XTERM-256COLOR\"\nCurrent device is iPad Simulator running iPhone OS 8.1\n> test\nUNKNOWN COMMAND = test ()\n> setwcolor\nUsage: setwcolor red green blue\n> setwcolor 1 0 0\nOK\n> quitConnection closed by foreign host.\n```\n" }, { "path": "Run-Tests.sh", "content": "#!/bin/bash -ex\n\n# Run GCDNetworking tests first\npushd \"GCDNetworking\"\n./Run-Tests.sh\npopd\n\nOSX_SDK=\"macosx\"\nif [ -z \"$TRAVIS\" ];
