+Digital Invisible Ink Toolkit is a Java steganography tool that can
+hide any sort of file inside a digital image (regarding that the
+message will fit, and the image is 24 bit colour). There are four
+highly customisable algorithms in the tool, as well as an open-source
+implementation of RS Analysis (an extremely good steganalysis method).
+The tool has the additional advantage of being able to simulate hiding
+- so you can get an accurate map of where the information is hidden.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
