+$NetBSD: README,v 1.2 1995/03/21 12:14:21 cgd Exp $
+
+Bog is a fairly portable simulation of Parker Brother's game of Boggle and
+is similar to the 4.[23] BSD "boggle" and Sun's "boggletool".
+Bog has not been derived from any proprietary code.
+It has been tested on the Sun 3 under SunOS 3.2 and on the Atari 1040ST (MWC).
+
+What You Need
+
+You will need curses/termcap and a large word list.
+The minix word list or /usr/dict/words will do nicely.
+The word list must already be sorted (you can use "sort -c" to check).
+
+Contents
+
+	README		- this file
+	Makefile
+	bog.man		- half-hearted man page (use the game's help command)
+	bog.h		- configuration and header info
+	bog.c		- machine independent game code
+	word.c		- machine independent word list routines
+	help.c		- (curses) help routine
+	mach.c		- (curses) display code
+	prtable.c	- ditto
+	timer.c		- machine dependent (os) input polling
+	mkdict.c	- convert a word list to a bog dictionary
+	mkindex.c	- create an index file for the bog dictionary
+	showdict.c	- print a bog dictionary to stdout
+
+Portability
+
+- I've tried to make bog.c (the program logic) independent of the I/O.
+  My plan was to make it straightforward to adapt the game to run under a
+  windowing system (eg., Suntools, GEM).  I have no plan to actually do this.
+  I've stuck to a small subset of the curses routines.
+- The program runs with the input in raw mode.
+- If you want the running timer you must #define TIMER in bog.h
+  and insert the input polling code in timer.c for your system.  There is
+  already code there for BSD, SYSV, and ATARI.
+
+Setup
+
+1. Check bog.h and Makefile and edit to fit your environment
+2. "make all"
+   This will make all the binaries and create the dictionary and index files
+3. Move "dict", "dict.ind", and "helpfile" to where you specified in bog.h
+4. Play away
+

+.SH NAME
+boggle \- word search game
+.SH SYNOPSIS
+boggle [-bd] [-s seed] [-t time] [-w length] [+[+]] [boardspec]
+.SH DESCRIPTION
+The object of
+.I boggle
+is to find as many words as possible on the Boggle board within the three
+minute time limit.
+A Boggle board is a four by four arrangement of Boggle cubes, each side of
+each cube displaying a letter of the alphabet or `qu'.
+Words are formed by finding a sequence of cubes (letters) that are in the
+game's dictionary.
+The (N+1)th cube in the word must be horizontally,
+vertically, or diagonally adjacent to the Nth cube.
+Cubes cannot be reused.
+Words consist solely of lower case letters and must be at least 3 letters long.
+.PP
+Command line flags can be given to change the rules of the game.
+The
+.B +
+flag allows a cube to be used multiple times, but not in succession.
+The
+.B ++
+flag allows the same cubes to be considered adjacent to itself.
+.B
+A seed other than the time of day is specified by
+.B -s#,
+where
+.B #
+is the seed.
+The time limit can be changed from the default 3 minutes by using the flag
+.B -t#,
+where
+.B #
+is the duration (in seconds) of each game.
+The minimum word length can be changed from 3 letters by specifying
+.B -w#,
+where
+.B #
+is the minimum number of letters to use.
+.PP
+A starting board position can be specified on the command line by
+listing the board left to right and top to bottom.
+.PP
+The
+.B -b
+flag puts
+.I boggle
+in batch mode.
+A
+.B boardspec
+must also be given.
+The dictionary is read from stdin and a list of words appearing in
+.B boardspec
+is printed to stdout.
+.PP
+Help is available during play by typing `?'.
+More detailed information on the game is given there.
+.SH BUGS
+If there are a great many words in the cube the final display of the words
+may scroll off of the screen.  (On a 25 line screen about 130 words can be
+displayed.)
+.sp 2
+No word can contain a 'q' that is not immediately followed by a 'u'.
+.sp 2
+When using the '+' or '++' options the display of words found in the board
+doesn't indicate reused cubes.

+
+[Note for users of versions of this program that do not display a timer:
+The first word entered after the timer has run out causes a list of all the
+words you found, the words you missed, and your running statistics to be
+displayed.]
+
+Any time you are prompted while the board is displayed you can type:
+                           <esc>word
+to see where "word" is on the board.
+
+Usage:
+    bog [-b] [-d] [-s#] [-t#] [-w#] [+[+]] [boardspec]
+
+    -b: batch mode (boardspec must be present); dictionary read from stdin
+    -d: debug mode
+    -s#: use # as the random number seed
+    -t#: time limit is # seconds instead of default 180
+    -w#: minimum word length is # letters instead of default 3
+    +: can reuse a cube, but not twice in succession
+    ++: can reuse cubes arbitrarily
+    boardspec: the first board to use (use 'q' for 'qu'); e.g.:
+          bog nolezeebnqieegei
+.
+                            Default Rules
+
+A Boggle board is a four by four arrangement of Boggle cubes.
+You have 3 minutes to find as many words as possible in the Boggle board.
+Words are formed by finding a sequence of cubes (letters) that are in the
+game's dictionary.  The (N+1)th cube in the word must be horizontally,
+vertically, or diagonally adjacent to the Nth cube.  Cubes cannot be reused.
+Words consist solely of lower case letters and must be at least 3 letters long.
+.
+                           Options
+
+Command line flags can be given to change the rules of the game.
+The '+' flag allows a cube to be used multiple times, but not in succession.
+The '++' flag makes each cube adjacent to itself.
+The time limit can be changed from the default 3 minutes by using the flag
+'-t#', where # is the duration (in seconds) of each game.
+The minimum word length can be changed from 3 letters by specifying 'w#',
+where # is the minimum number of letters to use.
+.
+                           Bugs and Limitations
+
+The following bugs and problems are known to exist:
+
+- If there are a great many words in the cube the final display of the words
+  may scroll off of the screen.  (On a 25 line screen about 130 words can be
+  displayed.)
+
+- Computing the complete word list can be too slow on small machines.
+
+- No word can contain a 'q' that is not immediately followed by a 'u'.
+
+- When using the '+' or '++' options the display of words found in the board
+  doesn't indicate reused cubes.
