override-end-of-line-style _ « "none"
Specifies whether the end-of-line style of all buffers should be overridden when writing them out to files. The default value is none, meaning that the buffer-specific attribute settings specified by current-buffer-end-of-line-style are not overridden. If override-RMS-record-attribute is set to one of "crlf" or "lf", then all buffers will be written out with the specified style, regardless of the value of current-buffer-end-of-line-style.
override-RMS-record-attribute _ « "none"
We recommend you use the variable override-end-of-line-style to set the end-of-line style rather then use the RMS variables.
Specifies whether the RMS attributes of all buffers should be overridden when writing them out to files. The default value is none, meaning that the buffer-specific attribute settings specified by current-buffer-RMS-record-attribute are not overridden. If override-RMS-record-attribute is set to one of stream, stream-lf or stream-cr, then all buffers will be written out with the specified attribute, regardless of the value of current-buffer-RMS-record-attribute.
