Also, sort the options strictly alphabetically ("r" before "raw").

 The default list of columns may be extended if _list_ is specified in the format _+list_ (e.g., *zramctl -o+COMP-RATIO*).
 
-*-p*, *--algorithm-params*::
-Set the algorithm parameters, for example, *level=9 dict=/etc/dictionary* to set compression level and pre-trained dictionary. Parameters are algorithm specific.

 Output all available columns.

+*-r*, *--reset* _zramdev_...::
+Reset the specified zram device(s).
+The settings of a zram device can be changed only after a reset.

 *--raw*::
 Use the raw format for status output.
 
-*-r*, *--reset*::
-Reset the options of the specified zram device(s). Zram device settings can be changed only after a reset.
-
 *-s*, *--size* _size_::
 Create a zram device of the specified _size_. Zram devices are aligned to memory pages; when the requested _size_ is not a multiple of the page size, it will be rounded up to the next multiple. When not otherwise specified, the unit of the _size_ parameter is bytes.
