Version 1.14
	- Fixed the "give away black moves" statistics

Version 1.13
	- fixed a ataris-that-could've-been-confused-for-suicide

Version 1.12
	- fixed bug where undoing a pass would result in placing stones of
	  the wrong color

Version 1.11
	- Improved percentages quite a bit
	- Added komi and handicap reporting
	- Stopped adding both "last move" markers when not giving away
	  a move

Version 1.10
	- Added a square on the 2nd to last move.  This is a bit more convenient
	  when in give-away-black mode, for example.  Otherwise, I wound up
	  clicking back a lot to see what the move I couldn't guess was, and
	  sometimes I even used it when I guessed correctly :)

Version 1.09
	- Fixed score reporting (from sgf, no computed)
	- Fixed percentage; it was broken by guess-only-white (EG)

Version 1.08
	- Added ability to guess moves of only white or only black if desired

Version 1.07
	- Added reporting of "venue" from "PC" in the sgf 

Version 1.06
	- Fixed a bug where the same close guess could be made more than once per
	  turn.

Version 1.05
	- Added players' ranks to the display.  Began including a redhat 7
	executable.

Version 1.04
	- Far off guesses are still marked with X's, but now close guesses are
	  marked with a small filled in square

Version 1.03
	- added reference in the README to a BGJ article about studying pro games.
	- fixed win-by-points vs resignation, added win by time

Version 1.02
	- removed a bug where sometimes the last position guessed was counted as
	  as a stone for purposes of group removal

Version 1.01
	- Added a spinner thingy to select the max number of guesses per move

Version 1.0
	- Basically just 0.993 renamed.  Some small changes in the README.
	- I've been using this version fairly regularly for some time now,
	  without any big urges to add anything, so it feels like a 1.0

Version 0.993
	- Split some repeated code into fmt_stats().  Added a percentage of correct
	  guesses.

Version 0.992
	- Removed some inconsistent whitespace
	- Reorganized main() a little
	- Added a file selection for the SGF file, if one isn't given on the
	  command line

Version 0.991
	- Added a more descriptive title to the window

Version 0.99
	- Added appropriate sensitivity for forward, back and pass buttons.
	- Fixed bug where sometimes a pass would lead to an off board "move"

Version 0.98
	(unreleased version)
	- fixed a bad memory leak in remove_if_no_liberties.
	- Added "forward" and "back" buttons, to allow backing up to study
	  what just happened a bit.

Version 0.97
	- Moved move # and guess # after date, so all frequently changing fields
	  next to each other
	- Added a note about who won by how much (or resignation), if the
	  SGF record includes it.

Version 0.96
	- removed a condition where markup was deleted from a position that isn't
	  on the board
	- removed chord on incorrect pass
	- display the names of the players, if available in the SGF
	- added event and date labels

Version 0.95
   - Updated README.

Version 0.93
   - Moved "run" rule to non-default position in kentou/Makefile
   - Changed to setenv DISPLAY to :0 if came in as unix:0, because unix:0
     confuses esound on redhat 6.1
   - initial pass support added.  pass doesn't erase markup yet, and passing
     after game end still gives a chord
   - pass erases markup
   - passing after game end no longer gives chord

Version 0.92
   - Removed "handicap is" printf.
   - Fixed a typo in the README
   - Added autoconf support (./configure)
   - Added optional esound support for gnome users.  Correct guesses get a
     bing, incorrect guesses get a anticipatory chord

Version 0.91
   Added a comment to the README about building with older versions of GTK+.
   Added a `gtk-config --cflags` to gtkgoboard/Makefile.
   Added a "that was (not) within 3 stones of the correct move" label
   Added a "correct - took n guesses" message

Version 0.90
   Added a number to the cursor, so you can tell which guess number you're
   on without moving your eyes away from the action.  Added handicaps,
   borrowing the algorithm for stone placement from cgoban.

   Changes to consider:
   - announce a bit more noticably when the correct move is guessed.
     sometimes it isn't immediately obvious that the answer was guessed.
   - make correct answer flash a while before removing incorrect answers
   - add a "give up" button for the current move?

Version 0.14
   Played most of the way through a real game.  Discovered that kentou
   has the same color problems baduki does - sometimes the black stones
   colorings get messed up.

   main.c became kentou.c.  This isn't looking like a multi .c project
   (as far as the code I'm writing, anyway).

   Eliminated reguesses.  Turned off cursor overtop of guesses.

   Changes to do:
   - handicap

   Changes to consider:
   - announce a bit more noticably when the correct move is guessed.
     sometimes it isn't immediately obvious that the answer was guessed.
   - make correct answer flash a while before removing incorrect answers
   - add a "give up" button for the current move?
   - add a number on the cursor, so you don't have to look to the side to
     see how many guesses you have left

Version 0.13
   Added triangle on previous move

   Changes to do:
   - handicap

   Changes to consider:
   - announce a bit more noticably when the correct move is guessed.
     sometimes it isn't immediately obvious that the answer was guessed.

Version 0.12
   Finished (?) group removal - the stones are actually removed now.

   Changes to do:
   - mark previous move.  Perhaps previous two moves.
   - handicap

   Changes to consider:
   - announce a bit more noticably when the correct move is guessed.
     sometimes it isn't immediately obvious that the answer was guessed.

Version 0.11
   Switched to "IGS" coordinates (skip "I")
   Finally tried kentou with a real game (part way through).  Half way done
   with removing captured groups - it's detecting 0 liberty groups, but not
   actually removing them.

   Changes to do:
   - mark previous move.  Perhaps previous two moves.
   - handicap
   - capturing

   Changes to consider:
   - announce a bit more noticably when the correct move is guessed.
     sometimes it isn't immediately obvious that the answer was guessed.

Version 0.10
   Consolidated some common code into a "do_stuff" procedure.  Added an
   average number of guesses calculation and display.

   Changes to do:
   - handicaps
   - capturing

Version 0.09
   Removed a bunch of debugging printf's.  Fixed some capitalization in
   move # label.  Changed box packing so board gets stretched, but labels
   don't.  Added a "Quit" button.  Added giving of correct answer after
   10th incorrect guess.

   Changes to do:
   - handicaps
   - capturing

Version 0.08
   Renamed board.xpm to kentou.xpm.  Added label to the right of the board
   that says (EG) "move #1, guess #1" or "end of game".  Rearranged
   hbox/vbox stuff.

Version 0.07
   Eliminated guessing after last move of the game.  Realized I'm going to
   have to do something about passing.  Added gtkrc stuff to main.c and
   install rule in Makefile.

Version 0.06
   Added x's for incorrect guesses.  Added code to remove x's after a
   correct guess.  Added do-nothing if for the last guess, which
   needs to be a special case.  Deleted code for removing stones; once
   a stone is placed, it should remain there unless captured.  We don't
   handle captured stones yet.

Version 0.05 and before 
   Reads SGF file, eliminates variations, displays board on which you can
   add and delete stones.  No guessing, no markup.
