 %description
 Algorithm::Combinatorics is an efficient generator of combinatorial
 sequences. Algorithms are selected from the literature (work in progress,
-see the /REFERENCES manpage). Iterators do not use recursion, nor stacks,
-and are written in C.

 Tuples are generated in lexicographic order, except in 'subsets()'.
