+MVEDIT
+======
+
+Move/delete multiple files at once!
+
+This opens an editor with one line per file of the current directory.
+
+* Editing the filename on the line renames the file.
+* Emptying the line deletes the file.
+
+Happy directory editing!
+
+Contribute
+==========
+
+Any help is welcomed, especially with the bugs :)
+
+See Bugs below, or TODO 's in the file.
+
+Bugs
+======
+
+Beware, special things like exchanging the names of two files or moving two
+files to the same filename is still not handled.
