+Syntax
+------
+
+Commands are usually terminated with a newline. Long command can be
+entered using sh style *here documents*. The format of here-documents
+is:::
+
+   << word
+	here document
+   word
+
+*word* can be any continuous string choosen to make sure it doesn't
+appear naturally in the following *here document*.
+
+When using the here document style of input there are no restrictions
+on lenght. When using newline-terminated commands maximum lenght is
+limited by the varnishd parameter *cli_buffer*.
+
+When commands are newline terminated they get *tokenized* before
+parsing so if you have significant spaces enclose your strings in
+double quotes. Within the quotes you can escape characters with
+\\. The \n, \r and \t get translated to newlines, carrage returns and
+tabs. Double quotes themselves can be escaped with a backslash.
+
+To enter characters in octals use the \\nnn syntax. Hexadecimals can
+be entered with the \\xnn syntax.
