+The following is an example of some data this script might parse.

+    #define length_trivial_usage \
+            "STRING"
+    #define length_full_usage \
+            "Prints out the length of the specified STRING."

+            "5\n"
+
+Each entry is a cpp macro that defines a string.  The macros are
+named systematically in the form:
+
+    $name_$type_usage
+
+$name is the name of the applet.  $type can be "trivial", "full", "notes",
+or "example".  Every documentation macro must end with "_usage".
+
+The definition of the types is as follows:
+
+=over 4
+
+=item B<trivial>
+
+This should be a brief, one-line description of parameters that
+the command expects.  This will be displayed when B<-h> is issued to
+a command.  I<REQUIRED>
+
+=item B<full>
+
+This should contain descriptions of each option.  This will also
+be displayed along with the trivial help if BB_FEATURE_TRIVIAL_HELP
+is disabled.  I<REQUIRED>
+
+=item B<notes>
+
+This is documentation that is intended to go in the POD or SGML, but
+not be output when a B<-h> is given to a command.  To see an example
+of notes being used, see init_notes_usage.  I<OPTIONAL>
+
+=item B<example>
+
+This should be an example of how the command is acutally used.
