+    (description
+     "This package implements NHexl mode, a minor mode for editing files
+in hex dump format.  The mode command is called @command{nhexl-mode}.
+
+This minor mode implements similar functionality to @command{hexl-mode},
+but using a different implementation technique, which makes it
+usable as a \"plain\" minor mode.  It works on any buffer, and does
+not mess with the undo log or with the major mode.
+
+It also comes with:
+
address@hidden
address@hidden @command{nhexl-nibble-edit-mode}: a \"nibble editor\" minor 
mode, where
+the cursor pretends to advance by nibbles (4-bit) and the self-insertion keys
+(which only work for hex-digits) will only modify the nibble under point.
address@hidden @command{nhexl-overwrite-only-mode}: a minor mode to try and 
avoid
+moving text.  In this minor mode, not only self-inserting keys overwrite
+existing text, but commands like `yank' and @command{kill-region} as well.
address@hidden It overrides @code{C-u} to use hexadecimal, so you can do 
@code{C-u a 4
+C-f} to advance by #xa4 characters.
