I wasn't going to chime in, but I had to reply to at least one of the previous
Regardless of whether the language parsing could be a problem as Rene pointed
out, the arg-type: value1 value2 thing just looks plain ugly and a lot
different from what is used currently. Personally, I like the suggestions
that Johan is making, such that we would have the following (including the 
portion in the requirements):
: parsers.cpp # By position
[ target-builds has_long_long : "skipping boost.math long long" ]
: usage-requirements <define>BOOST_ALL_NO_LIB=1
: description "Does something about dashes on command line"
: license "BSL 1.0"
I really don't like the overuse of the ':' character. The above looks a lot
more like 'project' and is much easier to understand and use than either the
current format or some of the other suggestions. Furthermore, because we are
not introducing a new concept for the ':' character, we don't add any more
confusion especially when you might want to put a conditional as demonstrated
above in the 'default-build' portion.
