+~~~~~~~~~~~~~~~
+
+These three lines poems are fun to write and fit nicely on a tiny screen.
+
+If there is a file called haiku.txt in the flash filesystem then this app
+allows it to be displayed three lines at a time using the pager.
+
+This application also (optionally) loads an icon from the filesystem allowing
+to be customized to match whether theme your verses are based around.
