Hugs home page broken

While checking the links from my own pages, I noticed that the link:

  http://www.haskell.org/hugs/

gives a directory listing instead of a home page.

The home page is there however.  It is listed as index.htm and clicking on it 
gives the expected page.

I suspect the problem can be fixed by either one of:

1) Rename index.htm to index.html
2) Tweak the configurations of haskell.org's web server to treat
   either index.html _or_ index.htm as the default page in a directory.
