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.

Towers
|
|
<p>
|
|
Fill in the grid with towers whose heights range from 1 to the grid
|
|
size, so that every possible height appears exactly once in each row
|
|
and column, and so that each clue around the edge counts the number
|
|
of towers that are visible when looking into the grid from that
|
|
direction. (Taller towers hide shorter ones behind them. So the
|
|
sequence 2,1,4,3,5 would match a clue of 3 on the left, because the
|
|
1 is hidden behind the 2 and the 3 is hidden behind the 4. On the
|
|
right, it would match a clue of 1 because the 5 hides everything
|
|
else.)
|
|
<p>
|
|
To place a tower, click in a square to select it, then type the
|
|
desired height on the keyboard. To erase a tower, click to select a
|
|
square and then press Backspace.
|
|
<p>
|
|
Right-click in a square and then type a number to add or remove the
|
|
number as a pencil mark, indicating tower heights that you think
|
|
<em>might</em> go in that square.
