	+Dear reader, in this document we will see differents command line
	+software which can be used to connect to a gopher server.
	+
	+
	+Printf + netcat
	+===============
	+
	+It's possible to write request "by hand" using printf to format the
	+request string and then netcat to send it to the remote server.
	+
	+A request of the file "/tutorials/cmdline.txt" will looks like this :
	+
	+ printf "/tutorials/cmdline.txt" \| nc somedomain.com 70
	+
	+You will get the server answer directly into your output. Be careful
	+if you ask binary files, it will be displayed on your screen, this is
	+not something a regular user want. If you want to download a binary
	+file, you can redirect the output to a file using ">" or pipe it to
	+another software (or using tee for both at the same time).
	+
	+The following example will download a music file, save it on the
	+filesystem and play it with mpv while downloading.
	+
	+ printf "/some_music.ogg" \| tee saved_music.ogg \| mpv -
	+
	+You may have seen that the data type is not part of the request
	+string, this is because it is only useful for the client to decide how
	+to handle the content. In the current case, the client is YOU, so if
	+you ask a menu and you want to download a file which has been tagged
	+with type "I" then you should use the right process to deal with an
	+image file.
	+
	+
	+Curl
	+====
	+
	+It is possible to use curl to connect to a gopher server, most of its
	+options are supported, like timeout or traffic shaping. You need to
	+pass a full url with "gopher://" at the start to curl to tell it you
	+want to request a gopher server.
	+
	+By default, curl will output the server result to stdout. Explanations
	+can be found in the previous section about this.
