    (description
     "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.")
