+# Battleships
+
+CP/M port of the Unix game.

+Copyright:
+ * bs.c - original author: Bruce Holloway
+ *              salvo option by: Chuck A DeGaul
+ * with improved user interface, autoconfiguration and code cleanup
+ *              by Eric S. Raymond <esr@snark.thyrsus.com>
+ * v1.2 with color support and minor portability fixes, November 1990
+ * v2.0 featuring strict ANSI/POSIX conformance, November 1993.
+ * v2.1 for Linux, October 1994.
+ * Slipstreamed in fixes to make it gcc -Wall clean, May '95.
+ * fairly seriously hacked for Hitech C and CP/M, rjm 95/8/14
+ 
+I found it as part of the ZCN repository: https://github.com/jamesots/zcn
+
+The C source has been modified for VT100 compatibility and some minor
+changes have been made by me (Anna Christina Naß <acn@acn.wtf>.
+
+``bs.com`` is the compiled binary.
+
+See the ``*.txt`` files for more information.
+
+## Modes
+
+* ``-b`` selects a "blitz" variant
+* ``-s`` selects a "salvo" variant
+* ``-c`` permits ships to be placed adjacently
+
+The "blitz" variant allows a side to shoot for as long as
+it continues to score hits.
+
+The "salvo" game allows a player one  shot  per  turn  for
+each  of his/her ships still afloat.  This puts a premium
+scoring hits early and knocking out some ships   and  also
+makes  much harder the situation where you face a superior
+force with only your PT-boat.
+
+## Keys
+
+To position your ships: move the cursor to a spot, then type the first letter of a ship 
+(using CAPITAL letters) type to select it, then type a direction ([hjkl] or [4862]),
+indicating how the ship should be pointed.
+You may also type a ship letter followed by `r' to position it randomly, or type `R' to
+place all remaining ships randomly.
+
+Navigation and aiming keys:
+
+    yz k u    7 8 9
+      \|/      \|/
+     h-+-l    4-+-6

+     b j n    1 2 3

+| Key   | Action                   | Key       | Action                   |
+| ----- | ------------------------ | --------- | ------------------------ | 
+| h / 4 | move left                | y / z / 7 | move up+left             |
+| l / 6 | move right               | b / 1     | move down+left           |
+| j / 2 | move down                | u / 9     | move up+right            |
+| k / 8 | move up                  | n / 3     | move down+right          |
+| r     | place this ship randomly | R         | place all ships randomly |
+| ^L    | screen redraw            | Q         | quit game                |
+
+## Compiling
+
+HiTech C has been used to compile it, but it needs a lot of free memory (TPA).
+
+For compiling, I used the command ``c bs.c`` in CP/M.

+Battleships is an intrinsically silly game, but I couldn't resist fixing this
+sucker. It now has a purely visual interface (you place ships and call for
+shots by moving the cursor around the board using the standard yuhjklbn keys).
+
+The default game now disallows placement of ships so that they touch. A new
+-c option is available to force the older behavior.
+
+I also removed the `seemiss' option (now always on) and `ask' (which is only
+useful for cheating). And I ifdefed out the ditsy opening screen; if you want
+it back, compile with -DPENGUIN. One strike against featureitis...
+
+The code now lints as clean as the broken SysV curses lint library will let it.
+
+Some #ifdefs in the code should result in the right things being done for
+BSD or USG systems. They key off A_UNDERLINE.  If you're using the Linux
+ncurses library, tell the makefile.
+
+This was probably a waste of a day or so. But what the hack -- rewriting the
+strategy robot as an FSM was fun, and maybe the interface will set a good
+example for the next guy.
+
+<*** FLAME ON ***>
+
+People who write termcap games that require you to enter #@!!#$! coordinates
+rather than doing the natural pick-and-place with cursor motions should be
+stuffed in suits and condemned to write COBOL for the rest of their days...
+
+<*** FLAME OFF ***>
+
+O.K., I feel better now that I've got that off my chest...
+
+November 1993: I've added function key support, and ANSI/POSIXized the code.

+This is a version of Battleships played on a 10x10 grid, with you
+playing against the computer. There's a reasonable amount of onscreen
+help, so you should be able to figure out how to work it pretty
+quickly.
+
+It's a port of a Unix curses version hacked by a few different people.
+A formatted version of the man page (documentation) is given below,

+DESCRIPTION
+       This  program  allows you to play the familiar Battleships
+       game against the computer on a 10x10 board. The  interface
+       is  visual  and  largely self-explanatory; you place your
+       ships and pick your shots by moving the cursor around  the
+       `sea'  with  the rogue/hack motion keys hjklyubn.  If your
+       UNIX has a modern (non-BSD) curses, your arrow  keys  will
+       also work.
+
+       Note  that  when selecting a ship to place, you must type
+       the capital letter (these are, after all, capital  ships).
+       During  ship  placement, the  `r'  command may be used to
+       ignore the current position and randomly place  your  cur-
+       rently  selected ship.   The  `R'  command  will place all
+       remaining ships randomly. The ^L command (form feed, ASCII
+       12) will force a screen redraw).
+
+       The command-line arguments control game modes.
+
+            -b selects a `blitz' variant
+            -s selects a `salvo' variant
+            -c permits ships to be placed adjacently
+
+       The  `blitz' variant allows a side to shoot for as long as
+       it continues to score hits.
+
+       The `salvo' game allows a player one  shot  per  turn  for
+       each  of his/her ships still afloat.  This puts a premium
+       scoring hits early and knocking out some ships   and  also
+       makes  much harder the situation where you face a superior
+       force with only your PT-boat.
+
+       Normally, ships must be separated by at least  one  square
+       of  open water.  The  -c  option  disables this check and
+       allows them to close-pack.
+
+       The algorithm the computer uses once it has found  a  ship
+       to sink is provably optimal.  The dispersion criterion for
+       the random-fire algorithm may not be.
