 @section Tags Tables
 @cindex tags and tag tables
 
-  A @dfn{tag} is a named subunit of a program or of a document.  In
-program source code, tags are syntactic elements of the program:
-functions, subroutines, data types, macros, etc.  In a document, tags
-are chapters, sections, appendices, etc.
-
-  A @dfn{tags table} records the names of the tags extracted from the
-source code of a certain program or from a certain document.  Each tag
-is listed together with the file name on which it is defined, and the
-position of the tag in that file.  Tags extracted from generated files
-reference the original file from which they were generated, rather
-than the file from which these tags were extracted.  Examples of
-generated files include C files generated from Cweb source files, from
-a Yacc parser, or from Lex scanner definitions; @file{.i} preprocessed
-C files; and Fortran files produced by preprocessing @file{.fpp}
-source files.
-
-  Tags tables are produced by scanning a document or the source code
-of a program with a special program called @samp{etags}, and stored in
-files called @dfn{tags table files}.  The conventional name for a tags
-table file is @file{TAGS}.

+the tags to files called @dfn{tags table files}, or @dfn{tags file} in
+short.  The conventional name for a tags file is @file{TAGS}.
 
   Emacs uses the information recorded in tags tables in commands that
-search or replace through multiple files: these commands use the names
-of the source files recorded in the tags table to know which files to
-search.  Other commands, such as @kbd{M-.}, which finds the definition
-of a function, use the recorded information about the function names
-and positions to find the source file and the position within that
-file where the function is defined.
