+This is a low level function that will separate the headers from the body
+of an encoded message.  It will also translate the headers into a mapping.
+It will however not try to analyze the meaning of any particular header,
+This also means that the body is returned as is, with any transfer-encoding
+intact.  It is possible to call this function with just the header part
+of a message, in which case an empty body will be returned.
+<p>
+The result is returned in the form of an array containing two elements.
+The first element is a mapping containing the headers found.  The second
+element is a string containing the body.
