that is one of the things you can do with versions -- figure out which 
one is larger than the other.

i mean that also, since that is The Next Step that module::build 
introduced.

for certain values of 'you' (drmath), this has already been done.. so 
yes, that's possible, but not the point here :)

standard and syntax, and a common place to put this...
if we can make it into a standard, copy/pasting the code isn't so 
bad... if we don't make it into a standard, well, we get what we have 
right now :)

not relevant i think :) we have our own quirky version system, and we 
have had 'only' for a little while now, which makes it possible to use 
ranges of versions
(i forgot to mention 'only' earlier, shame on me).
