+      An "ID database" is a binary file containing a list of file
+      names, a list of tokens, and a sparse matrix indicating which
+      tokens appear in which files.
+
+      With this database and some tools to query it, many
+      text-searching tasks become simpler and faster.  For example,
+      you can list all files that reference a particular `\#include'
+      file throughout a huge source hierarchy, search for all the
+      memos containing references to a project, or automatically
+      invoke an editor on all files containing references to some
+      function or variable.  Anyone with a large software project to
+      maintain, or a large set of text files to organize, can benefit
+      from the ID utilities.
+
+      Although the name `ID' is short for `identifier', the ID
+      utilities handle more than just identifiers; they also treat
+      other kinds of tokens, most notably numeric constants, and the
+      contents of certain character strings.
