+// WordKeyInfo.h
+//
+// NAME
+// information on the key structure of the inverted index.
+//
+// SYNOPSIS
+//
+// Use the WordKey::NField() method instead.
+//
+// DESCRIPTION
+//
+// Describe the structure of the index key (<i>WordKey</i>).
+// The description includes the layout of the packed version
+// stored on disk.
+//
+// CONFIGURATION
+//
+// wordlist_wordkey_description <desc> (no default)
+//   Describe the structure of the inverted index key.
+//   In the following explanation of the <i><desc></i> format
+//   mandatory words are
+//   in bold and values that must be replaced in italic.
+//   <br>
+//   <b>Word</b>/<i>name bits</i>[/...]
+//   <br>
+//   The <i>name</i> is an alphanumerical symbolic name for the key field.
+//   The <i>bits</i> is the number of bits required to store this field.
+//   Note that all values are stored in unsigned integers (unsigned int).
