Simon Tatham e2c84a5fd2 Introduce a mechanism in this source tree for building the container
web pages for the Java applets. Previously, those have all been
maintained by hand in my website's svn area, which is a bit silly. Now
we have a file per puzzle in the 'html' subdirectory which contains
the puzzle's name, one or two attributes, and the instructions snippet
to go below the puzzle applet; and then there's a Perl script that
builds all the real web pages out of that by adding in the parts
common across all files: the header, footer, and middle fragment with
the <applet> tag and resizing bits and pieces.

One piece _not_ checked in here is the footer text specific to my
hosting at chiark, which I think does still belong in the www area. So
Buildscr doesn't actually build the web pages; it just delivers the
bits and pieces by which my nightly snapshot script will be able to
run the program that _does_ build them, passing that footer as an
extra argument.

Black Box
<p>
Determine where the hidden balls are in the box, by observing the
behaviour of light beams fired into the box from the sides.
<p>
Click in a square around the edge of the box to send a beam into the
box. Possible results are 'H' (the beam hit a ball dead-on and
stopped), 'R' (the beam was either reflected back the way it came or
there was a ball just to one side of its entry point) or a number
appearing in two squares (indicating that the beam entered one of
those squares and emerged from the other).
<p>
Click in the middle of the box to place your guessed ball positions.
When you have placed enough, a green button will appear in the top
left; click that to indicate that you think you have the answer.
You can also right-click to mark squares as definitely known.
