+Description
+===========
+
+Bulkrename allows you to pipe a list of filenames and to rename them
+interactively within your editor. It is inspired by ranger's bulkrename
+command (see http://nongnu.org/ranger/).
+
+Why ?
+=====
+
+When dealing with a great number of files, or having the same modification to
+do a lot of time it it often easier to do it in our well-known editor.
+
+Documentation
+=============
+
+Just pipe a list of files to bulkrename.
+
+If your $EDITOR environment variable is not set, vi will be called.
+
+License
+=======
+
+The code is under the WTFPL (see http://www.wtfpl.net/) mainly because I
+wanted to stay at 42 lines of code and the GPLv3 was too long.
