    (description
     "The GNU idutils package includes tools to create an index of textual
tokens used in a list of file names and then to query that index.  Thus, it
allows the user to, for example, find all the uses of a particular function
in a large programming project.  In addition to handling textual tokens, it
can also handle numeric constants and the contents of character strings.")
