well, never mind. i understood very well what you were pointing at (but 
of course felt the urge to get things right ;-))

i guess it is the same as ever:
1) normally i only use zexy (because most things i ever need are in 
there because they are in there because i need them)
2) this keeps me from having nameclashes on my machine: for instance i 
am using Gem a lot (no-na) but i don't want it in my .pdrc for testing 
purposes; using Gem+maxlib would result in the famous [scale]-problem 
which i am not very interested in (i mean: i am interested in the 
problem but not in having it)
3) thus i didn't know that the others existed. (even though it might 
seem strange that i did not realize that there was one in the iemlib)
4) i needed an object that not only wraps between [0,1) but between 2 
arbitrary numbers, e.g. [-pi, pi).

now that i have learned of [maxlib/wrap] i see that it provides exactly 
this; the only problem i see with it is, that it defaults to wrap 
between [0, 0) which is not very convenient.

anyhow, i am thinking about restructuring zexy a lot, and i might drop 
[wrap] then (as i see, that mine is probably the youngest)
