| * MacOS X has a proxy configuration module in System Preferences (on |

| * proxy settings for: |
| * |
| * \list |
| * \o FTP proxy |
| * \o Web Proxy (HTTP) |
| * \o Secure Web Proxy (HTTPS) |
| * \o Streaming Proxy (RTSP) |
| * \o SOCKS Proxy |

| * \o URL for Automatic Proxy Configuration (PAC scripts) |
| * \o Bypass list (by default: *.local, 169.254/16) |
| * \endlist |
| * |
| * The matching configuration can be obtained by calling SCDynamicStoreCopyProxies |
| * (from <SystemConfiguration/SCDynamicStoreCopySpecific.h>). See |
