  ah, excellent, this is important for me since, when i teach OE/YP,
one of the first things i do is distinguish between a "build" and
"nobuild" project directory ("nobuild" meaning configured only), and
use "bb" to show how much one can query about the project before any
compilation is done. this is amazingly useful.

rday

p.s. if readers don't know about "bb", i wrote a page on it once upon
a time:

  http://www.crashcourse.ca/wiki/index.php/Bb

i better go back and make sure it's up to date.
