+hexer (hex editor with vi-like UI)
+
+Hexer is a multi-buffer editor for binary files for Unix-like systems
+that displays its buffer(s) as a hex dump. The user interface is kept
+similar to vi/ex.
+
+If you don't like the default color scheme, copy one of the
+/usr/doc/$VERSION/rc/hexerrc.* files to ~/.hexerrc.
+
+The package also includes myc, a simple textmode calculator that's
+useful for hex <=> decimal conversions and bitwise operations.
