// A javascript port of my Perl string capitaliser. Possibly someone who is better at
// DOM scripting than me could make a script that would automatically apply this to any
// element styled with text-transform: uppercase.
// Again, the algorithm is too simple to be worth insisting on attribution, but if you
// do use this script anywhere, please attribute it to me in a comment block somewhere.

return true;
}
}
