  ** Etags changes.
  
+ *** New syntax for regular expressions, multi-line regular expressions.
+ The syntax --ignore-case-regexp=/REGEX/NAME/ is now undocumented and
+ retained only for backward compatibility.  The new equivalent syntax is
+ --regex=/REGEX/NAME/i.  More generally, it is --regex=/REGEX/NAME/MODS,
+ where `/NAME' is optional, as usual, and MODS is a string of 0 or more
+ characters among `i' (ignore case), `m' (multi-line) and `s'
+ (single-line).  The `m' and `s' modifiers behave as in Perl regular
+ expressions: `m' allows regexps to match more than one line, while `s'
+ (which implies `m') means that `.' matches newlines.  The ability to
+ span newlines allows writing of much more powerful regular expressions
+ and rapid prototyping for tagging new languages.
+ 
+ *** Regular expressions can use char escape sequences as in Gcc
+ The escaped character sequence \a, \b, \d, \e, \f, \n, \r, \t, \v,
+ respectively, stand for the ASCII characters BEL, BS, DEL, ESC, FF, NL,
+ CR, TAB, VT,

  will read from standard input and mark the produced tags as belonging to
  the file FILE.
