+"abbreviated:  NORTH to N, SOUTH to S, EAST to E, WEST to W, NORTHEAST to\n"
+"NE, NORTHWEST to NW, SOUTHEAST to SE, SOUTHWEST to SW, UP to U, and DOWN\n"
+"to D.  IN and OUT will also work in certain places.\n"
+"\n"
+"There are many differnet kinds of sentences used in Interactive Fiction.\n"
+"Here are some examples:\n"
+"\n"
+"> WALK TO THE NORTH\n"
+"> WEST\n"
+"> NE\n"
+"> DOWN\n"
+"> TAKE THE BIRDCAGE\n"
+"> READ ABOUT DIMWIT FLATHEAD\n"
+"> LOOK UP MEGABOZ IN THE ENCYCLOPEDIA\n"
+"> LIE DOWN IN THE PINK SOFA\n"
+"> EXAMINE THE SHINY COIN\n"
+"> PUT THE RUSTY KEY IN THE CARDBOARD BOX\n"
+"> SHOW MY BOW TIE TO THE BOUNCER\n"
+"> HIT THE CRAWLING CRAB WITH THE GIANT NUTCRACKER\n"
+"> ASK THE COWARDLY KING ABOUT THE CROWN JEWELS\n"
+"\n"
+"You can use multiple objects with certain verbs if you separate them by\n"
+"the word \"AND\" or by a comma.  Here are some examples:\n"
+"\n"
+"> TAKE THE BOOK AND THE FROG\n"
+"> DROP THE JAR OF PEANUT BUTTER, THE SPOON, AND THE LEMMING FOOD\n"
+"> PUT THE EGG AND THE PENCIL IN THE CABINET\n"
+"\n"
+"You can include several inputs on one line if you separate them by the\n"
+"word \"THEN\" or by a period.  Each input will be handled in order, as\n"
+"though you had typed them individually at seperate prompts.  For example,\n"
+"you could type all of the following at once, before pressing the ENTER (or\n"
+"RETURN) key:\n"
+"\n"
+"> TURN ON THE LIGHT. TAKE THE BOOK THEN READ ABOUT THE JESTER IN THE BOOK\n"
+"\n"
+"If the story doesn't understand one of the sentences on your input line,\n"
+"or if an unusual event occurs, it will ignore the rest of your input line.\n"
+"\n"
+"The words \"IT\" and \"ALL\" can be very useful.  For example:\n"
+"\n"
+"> EXAMINE THE APPLE.  TAKE IT.  EAT IT\n"
+"> CLOSE THE HEAVY METAL DOOR.  LOCK IT\n"
+"> PICK UP THE GREEN BOOT.  SMELL IT.  PUT IT ON.\n"
+"> TAKE ALL\n"
+"> TAKE ALL THE TOOLS\n"
+"> DROP ALL THE TOOLS EXCEPT THE WRENCH AND MINIATURE HAMMER\n"
+"> TAKE ALL FROM THE CARTON\n"
+"> GIVE ALL BUT THE RUBY SLIPPERS TO THE WICKED WITCH\n"
+"\n"
+"The word \"ALL\" refers to every visible object except those inside\n"
+"something else.  If there were an apple on the ground and an orange inside\n"
+"a cabinet, \"TAKE ALL\" would take the apple but not the orange.\n"
+"\n"
+"There are three kinds of questions you can ask:  \"WHERE IS (something)\",\n"
+"\"WHAT IS (something)\", and \"WHO IS (someone)\".  For example:\n"
+"\n"
+"> WHO IS LORD DIMWIT?\n"
+"> WHAT IS A GRUE?\n"
+"> WHERE IS EVERYBODY?\n"
+"\n"
+"When you meet intelligent creatures, you can talk to them by typing their\n"
+"name, then a comma, then whatever you want to say to them.  Here are some\n"
+"examples:\n"
+"\n"
+"> JESTER, HELLO\n"
+"> GUSTAR WOOMAX, TELL ME ABOUT THE COCONUT\n"
+"> UNCLE OTTO, GIVE ME YOUR WALLET\n"
+"> HORSE, WHERE IS YOUR SADDLE?\n"
+"> BOY, RUN HOME THEN CALL THE POLICE\n"
+"> MIGHTY WIZARD, TAKE THIS POISONED APPLE.  EAT IT\n"
+"\n"
+"Notice that in the last two examples, you are giving the characters more\n"
+"than one command on the same input line.  Keep in mind, however, that many\n"
+"creatures don't care for idle chatter; your actions will speak louder than\n"
+"your words.  \n";
