+dynamic options
+================
+
+Description
+-----------
+This patch adds a flag (`-dy`) which makes dmenu run the command given to it
+whenever input is changed with the current input as the last argument and
+update the option list according to the output of that command.
+
+By default dmenu does not let you change the option list after starting it,
+this patch adds support for that.
+It is best used with the -l flag.
+
+(ie. usage: `dmenu -dy ls` runs ls on whatever directory/file you are currently typing
+in dmenu and lets you select it)
