;;; In order to save space, some of the less common stream operations
;;; are handled by just one function, the MISC method. This function
;;; is passed a keyword which indicates the operation to perform.
;;; The following keywords are used:
-;;; :listen - Return the following values:
-;;; t if any input waiting.
-;;; :eof if at eof.
-;;; nil if no input is available and not at eof.
-;;; :unread - Unread the character Arg.
-;;; :close - Do any stream specific stuff to close the stream.
-;;; The methods are set to closed-flame by the close
-;;; function, so that need not be done by this
-;;; function.
-;;; :clear-input - Clear any unread input
+;;; :listen - Return the following values:
+;;; t if any input waiting.
+;;; :eof if at eof.
+;;; nil if no input is available and not at eof.
+;;; :unread - Unread the character Arg.

+;;; The methods are set to closed-flame by the close
+;;; function, so that need not be done by this
+;;; function.
+;;; :clear-input - Clear any unread input
;;; :finish-output,
-;;; :force-output - Cause output to happen
-;;; :clear-output - Clear any undone output
-;;; :element-type - Return the type of element the stream deals with.
-;;; :line-length - Return the length of a line of output.
-;;; :charpos - Return current output position on the line.
-;;; :file-length - Return the file length of a file stream.
-;;; :file-position - Return or change the current position of a
+;;; :force-output - Cause output to happen
+;;; :clear-output - Clear any undone output
+;;; :element-type - Return the type of element the stream deals with.
+;;; :line-length - Return the length of a line of output.

+;;; :file-length - Return the file length of a file stream.
+;;; :file-position - Return or change the current position of a
;;; file stream.
-;;; :file-name - Return the name of an associated file.
+;;; :file-name - Return the name of an associated file.
;;; :interactive-p - Is this an interactive device?
