The Emacs Manual and the Emacs Lisp Reference Manual describe the
syntax of regular expressions *in Emacs*, but _not_ the differences to
Perl REs, ...

,----[ (info "(emacs)Regexps") ]
| Syntax of Regular Expressions
| 
| This manual describes regular expression features that users typically

| Lisp programs; see *Note Regular Expressions: (elisp)Regular
| Expressions.
`----

(info "(emacs)Regexps"); <== Press C-x C-e here!
(info "(elisp)Regular Expressions"); <== Press C-x C-e here!

Probably also useful: `M-x re-builder RET'.

Bye, Reiner.
