+#!/bin/sh
+
+# Allow bulk operations on a list of selected files.
+# Usage: sel [command]
+# If no command is specified, shows the list of selected files
+# Commands:
+#	add [files|dirs|all]: add files to selection
+#	clear: clear selection
+#	cp: copy to current dir, possbily after editing filenames
+#	edit: open selection in editor
+#	mv: move to current dir, possbily after editing filenames
+#	rm: remove selected files and clear selection
+
+# Requires: dmenu (or similar), trashrm (optional)
+
+# TODO: add possibility of specifying file.
+# TODO 2: The usage of paste(1) is a bit of a hack, and for example it does
+# not work if filenames contain tab characters. Fix this.
