[boost] How to reverse a boost::tuple

I haven't been able to find any utility to any sensible metaprogramming
with boost::tuples's. In particular, I'm interested in having one of the

following (either will do):

1. Write a metaprogram that reverses a boost::tuple, i.e a construct
say reverse such that

reverse<Tuple>::type

is a tuple containing the same elements as Tuple but in reverse order.

2. Obtain a tuple type from a given Tuple containing all its members
excepts the last one, vg:

all_but_last<tuple<int,double,char> >::type == tuple<int, double>

Thanx for your help. Regards,
