No. If you do not declare the sitemap, then all the pages in the app will
be available, however you'll have to manually enforce access control and
manually build menus. You can also define particular directories as
"anything in this directory gets served."

It's been my experience that having a large site is a very good reason to
have SiteMap... you can have each module define its pages, access control,
etc. and roll that up into a nice menu.

That looks like a typo in the book. I'll fix it.

String and List are unrelated types. You can write if you want in
implicit conversion function but IMHO is not worth it.
Menu(Loc("Home", List("/"), "Home"))
For this construct Lift already has an implicit conversion
strLstToLink from a Seq[String] to a Link which is what Loc apply
expects.
So List[String] is expected because a path is not expressed as a plain
string but rather as a List of path parts.

To access a page you should put it in the SiteMap. You can choose to
not use SiteMap at all but rather work only with DispatchPF and so on,
but for a web application this is impractical.
>if so, when the website is large, the work may be tiring?
You only define the sitemap once. You can break it to modules etc.
that return specific lists of Menus but that's about application
design. If you're doing RIA style application you'll probably won't
need a tremendous amount of pages anyways.
