+The object of Boggle (TM Parker Bros.) is to find, within 3 minutes, as
+many words as possible in a 4 by 4 grid of letters.
+Words may be formed from any sequence of 3 or more adjacent letters
+in the grid. The letters may join horizontally, vertically,
+or diagonally. However, no position in the grid may be used
+more than once within any one word.
+In competitive play amongst humans, each player is given
+credit for those of his words which no other player has found.

+This program is intended for people
+wishing to sharpen their skills at Boggle.
+If you invoke the program with 4 arguments of 4 letters each,
+(e.g. "boggle appl epie moth erhd")
+the program forms the obvious Boggle grid and lists all the
+words from /usr/dict/words found therein.
+If you invoke the program without arguments, it will generate
+a board for you, let you enter words for 3 minutes, and then
+tell you how well you did relative to /usr/dict/words.

+In interactive play, enter your words separated by spaces, tabs, or newlines.
+A bell will ring when there is 2:00, 1:00, 0:10, 0:02, 0:01, and 0:00 time
+left.
+You may complete any word started before the expiration of time.
+You can surrender before time is up by hitting 'break'.
+While entering words, your erase character is only effective within the current
+word and your line kill character is ignored.

+Advanced players may wish to invoke the program with 1 or 2 +'s as the
+first argument. The first + removes the restriction that postions can only
+be used once in each word.
+The second + causes a position to be considered adjacent to itself
+as well as its (up to) 8 neighbors.
+Hit any key to begin.
