/*
 * MacOS X has a proxy configuration module in System Preferences (on
 * MacOS X 10.5, it's in Network, Advanced), where one can set the
 * proxy settings for:
 *
 * \list
 *   \o FTP proxy
 *   \o Web Proxy (HTTP)
 *   \o Secure Web Proxy (HTTPS)
 *   \o Streaming Proxy (RTSP)
 *   \o SOCKS Proxy
 *   \o Gopher 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
 * Apple's documentation:
