and I did not recommend it, but rather pointed out that with 
some mungeing, it was less dangerous that 'B A D'.  The '-p 
option' for post-processing a corpus, piece by piece requires 
the same loop avoidance alertness

as may be -- but the nice thing about a Unix-like environment 
with adequate fork and pipe facilities, is that one can have a 
powerful enough tool to shoot oneself in the foot, if that is 
your wish.  It is easy enough, with the sub-shell examples 
provided by me, to consult a translate function, or 
pre-computed table of recipients (single or multiple), and 
then feed that result into the disposition phase.  I used 
delivering recipies, but re-mailing ones are easy enough to 
drop in
