-;; Sequence-manipulation functions that complement basic functions
-;; provided by subr.el.
-;;
-;; All functions are prefixed with "seq-".
-;;
-;; All provided functions work on lists, strings and vectors.
-;;
-;; Functions taking a predicate or iterating over a sequence using a
-;; function as argument take the function as their first argument and
-;; the sequence as their second argument.  All other functions take
-;; the sequence as their first argument.
-;;
-;; All functions are tested in test/automated/seq-tests.el
