+;;; Commentary:
+
+;; 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.
+
+;;; Code:
+
+(if (version< emacs-version "25")
+    (require 'seq-24)
+  (require 'seq-25))
+
+(provide 'seq)
+;;; seq.el ends here
