+The SVG files in this directory are used to verify that certain CSS
+constructs are processed properly. These "tests" are un-automated; you
+have to view each diagram with the example program svgtiny_display_x11
+to see if they are rendered correctly.
+
+What is "correctly?"
+
+Each test should be simple enough that the correct behavior is not to
+hard for someone familiar with CSS to deduce. Hints may be given in
+the comment at the top of the file. Or, maybe you just open the same
+file in firefox and look at them side-by-side.
