How to review pkgng remote dir tree for package names

[Fbsd8]

Now that pkgng is on the road to becoming the default package method, 
need a way to scroll through the online pkg.freebsd.org pkg directory 
tree to locate packages that have new names.

I tried ftp to   http://pkg.freebsd.org/freebsd:10:x86:64/latest/All/ 
but don't think it likes "anonymous" login.

What is the preferable method of manual review.
