automatic coefficient / summand extraction

Hi there,

I have a linear term which can look like the following:

5 a +  3 b + (2 c + 5 a) / 7

I need to extract the individual variables and their coefficients. I.e. I  
want to end up with something like:

5 + 5            2
-----  a, 3 b,   - c
  7              7

If I have been blinded and it is very easy to achieve, I would greatly  
appreciate help.

Thank you,

Axel

P.s.: I'm not subscribed to this list, since I do not use Mathematica very  
often. Please send me email and I will summarize if that is customary on this  
list. I am under time pressure to finish this. Please don't flame too much if  
this list is not appropriate to post this question.
