So you prefer the first choice I gave of having a single delimited
section for the requirements. It's just the labels to use as delimiters
you don't like?

Of the above I don't particularly like "self:" it's not descriptive. I
know what it means, but I doubt a new user is going to understand it.
Same goes for "all:". I like the idea of using a composition of the
various labels, although I might prefer using the current composition
"," separator...

lib foo : foo.cpp :

Personally I like the "build" label. It indicative of when the
requirements are used, only when building the target. For the usage
requirements "users" is good, but it's not a currently familiar term. A
shorter, and corresponding term is "use". That matches the "<use>"
feature directly. The example:

lib foo : foo.cpp :

Can I take by your suggestion of "self:" etc, that you don't like the
current BBv2 labels of "requirements" and "usage-requirements"?
