# excerpt from the chromium help message:
#
#              Specify the HTTP/SOCKS4/SOCKS5 proxy server to use for requests.  This overrides any environment variables or settings picked via the options dialog.  An individual proxy server is specified
#              using the format:
#
#
#
#              Where <proxy-scheme> is the protocol of the proxy server, and is one of:
#
#                "http", "socks", "socks4", "socks5".
#
#              If the <proxy-scheme> is omitted, it defaults to "http". Also note that "socks" is equivalent to "socks5".
#
#              Examples:
#
#                --proxy-server="foopy:99"
#                    Use the HTTP proxy "foopy:99" to load all URLs.
#
#                --proxy-server="socks://foobar:1080"
#                    Use the SOCKS v5 proxy "foobar:1080" to load all URLs.
#
#                --proxy-server="socks4://foobar:1080"
#                    Use the SOCKS v4 proxy "foobar:1080" to load all URLs.
#
#                --proxy-server="socks5://foobar:66"
#                    Use the SOCKS v5 proxy "foobar:66" to load all URLs.
#
#              It is also possible to specify a separate proxy server for different URL types, by prefixing the proxy server specifier with a URL specifier:
#
#              Example:
#
#                --proxy-server="https=proxy1:80;http=socks4://baz:1080"
#                    Load https://* URLs using the HTTP proxy "proxy1:80". And load http://*
#                    URLs using the SOCKS v4 proxy "baz:1080".
