Yes, that's what I meant: the functionality remains for backward
compatibility until all clients have been upgraded for months/years,
but no one should define specialized methods on it anymore in new
code, and the functionality will go away eventually.

Reader is probably what it should be indeed. I don't know why I made

I suppose the return type is (or string null (eql :directory));
yes, it's a misnomer, a misdesign, and it should die.

Oops, I just made a few small changes to the manual. I hope they don't conflict.
PS: I also removed old merged branches from the repository, and
created new ones.
I invite you to merge in the renamed-bundle-op branch in which I
rename bundle-operation as promised, and also the build-op branch that
implements the strings as operation designator as well as renamed the
build-system function to build (but I think the consensus is to
further rename it to make). The standard-syntax branch is not ready
and contains previous experiments for syntax control, that I hope we
can complete and merge after the current release.
