- (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.")
