+
+	Do not use map.el in seq-tests.el
+
+	* packages/seq/tests/seq-tests.el: Do not use map.el.  map.el was 
+	introduced in Emacs 25.1, but seq.el is also available in GNU ELPA for

+
+	All functions in seq-25.el are wrapped in a `seq--when-emacs-25-p' to

+
+;; 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.
+;;
+;; seq.el can be extended to support new type of sequences.  Here are
+;; the generic functions that must be implemented by new seq types:
+;; - `seq-elt'
+;; - `seq-length'
+;; - `seq-do'
+;; - `seqp'
+;; - `seq-subseq'
+;; - `seq-into-sequence'
+;; - `seq-copy'
+;; - `seq-into'
+
+;;; Code:
+
+;; When loading seq.el in Emacs 24.x, this file gets byte-compiled, even if
+;; never used.  This takes care of byte-compilation warnings is emitted, by
+;; emitting nil in the macro expansion in Emacs 24.x.
