 Similar to @samp{New Game}, but allows you to specify a particular initial position 
 (according to a standardized numbering system)
 in chess variants which use randomized opening positions (e.g. Chess960).
-You can also press the @samp{Pick Fixed} button to let XBoard generate
-a random number for you.
-The thus selected opening position will then persistently be chosen on any following
-New Game command until you use this menu to select another. 
-Selecting position number -1 (or pushing the @samp{Randomize} button)
-will produce a newly randomized position on any new game.
-Using this menu item in variants that normally do not shuffle their opening position
-does cause these variants to become shuffle variants until you use the
-@samp{New Shuffle Game} menu to explicitly switch the randomization off,
-or select a new variant.

+@item -epd
+@cindex epd, option
+This option puts XBoard in a special mode for solving EPD test-suites,
+for the entire duration of the session.
+In this mode games are aborted after a single move,
+and that move will be compared with the best-move or avoid-move
+from the EPD position description from which the 'game' was started.
+Playing a best move counts as a win, playing an avoid move as a loss,
+and playing any other move counts as a draw.
+This option should be used in combination with match mode,
+and an EPD file of starting positions with an auto-incrementing index.
+Color assignment will be such that the first engine plays all moves,
+and the second engine will be never involved.
+The results for individual positions,
+as well as the time used for solving them,
+will be reported in the lower pane of the Engine Output window.
