8 I'm not really sure what you mean by "debug" versions. Are those
9 versions built with "-g"? In that case you don't need a USE flag, just
10 let the user add "-g" to CFLAGS (and "nostrip" to FEATURES).

18 Any idea what the difference in build time is? If it's minor, then just
19 do both. Just because something can be optional does not mean that it
20 must be optional.

34 In any event, would just ask vapier for his opinion, and do whatever he
35 says.
