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.

<p>
|
|
Draw a single closed loop by connecting together the centres of
|
|
adjacent grid squares, so that some squares end up as corners, some as
|
|
straights (horizontal or vertical), and some may be empty. Every
|
|
square containing a black circle must be a corner not connected
|
|
directly to another corner; every square containing a white circle
|
|
must be a straight which is connected to <em>at least one</em> corner.
|
|
<p>
|
|
Drag between squares to draw or undraw pieces of the loop.
|
|
Alternatively, left-click the edge between two squares to turn it on
|
|
or off. Right-click an edge to mark it with a cross indicating that
|
|
you are sure the loop does not go through it.
