-HTML DOCUMENTATION.
-
-    Please pass HTML files though HTML Tidy (http://tidy.sf.net) before
-    comitting. This has to important purposes:
-    - detecting bad HTML
-    - converting files to uniform indentation style, which inverses effect of
-      different editors and makes differences between revisions much smaller and
-      easy for review.
-
-    Alas, the way Tidy indents HTML differs between version. Please use the
-    version available at
-
-       http://tidy.sourceforge.net/src/old/tidy_src_020411.tgz
