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.
