Yes, I have noticed that dependency, too. However, I'm not sure what the
right thing to do is, as I'm unconvinced that running this
'check_manifest()' function as a test is such a good idea.
First, it requires Roundup to be built (and thus should be disabled when
run in the source tree), and second, the same function is run during the
build procedure itself, too.

In fact, I'm not sure I see the need for this function at all. As it
compares existing files with the files from MANIFEST (a file that itself
has been built by listing existing files matching some glob pattern), it
seems a bit redundant.
Richard, do you have an opinion on this ? Can thie check_manifest()
function go ?
