+** The new package rx.el provides an alternative sexp notation for
+regular expressions.
+
+- Function: rx-to-string SEXP
+
+Translate SEXP into a regular expression in string notation.
+
+- Macro: rx SEXP

+
+`(and SEXP1 SEXP2 ...)'
+ matches what SEXP1 matches, followed by what SEXP2 matches, etc.
+
+`(submatch SEXP1 SEXP2 ...)'
+ like `and', but makes the match accessible with `match-end',
+ `match-beginning', and `match-string'.
+
+`(group SEXP1 SEXP2 ...)'
+ another name for `submatch'.
+
+`(or SEXP1 SEXP2 ...)'
+ matches anything that matches SEXP1 or SEXP2, etc. If all
+ args are strings, use `regexp-opt' to optimize the resulting
+ regular expression.
+
+`(minimal-match SEXP)'
+ produce a non-greedy regexp for SEXP. Normally, regexps matching
+ zero or more occurrances of something are \"greedy\" in that they
+ match as much as they can, as long as the overall regexp can
+ still match. A non-greedy regexp matches as little as possible.
+
+`(maximal-match SEXP)'
+ produce a greedy regexp for SEXP. This is the default.
+
+`(zero-or-more SEXP)'
+ matches zero or more occurrences of what SEXP matches.
+
+`(0+ SEXP)'
+ like `zero-or-more'.
+
+`(* SEXP)'
+ like `zero-or-more', but always produces a greedy regexp.
+
+`(*? SEXP)'
+ like `zero-or-more', but always produces a non-greedy regexp.
+
+`(one-or-more SEXP)'
+ matches one or more occurrences of A.
+
+`(1+ SEXP)'
+ like `one-or-more'.
+
+`(+ SEXP)'
+ like `one-or-more', but always produces a greedy regexp.
+
+`(+? SEXP)'
+ like `one-or-more', but always produces a non-greedy regexp.
+
+`(zero-or-one SEXP)'
+ matches zero or one occurrences of A.
+
+`(optional SEXP)'
+ like `zero-or-one'.
+
+`(? SEXP)'
+ like `zero-or-one', but always produces a greedy regexp.
+
+`(?? SEXP)'
+ like `zero-or-one', but always produces a non-greedy regexp.
+
+`(repeat N SEXP)'
+ matches N occurrences of what SEXP matches.
+
+`(repeat N M SEXP)'
+ matches N to M occurrences of what SEXP matches.
+
+`(eval FORM)'
+ evaluate FORM and insert result. If result is a string,
+ `regexp-quote' it.
+
+`(regexp REGEXP)'
+ include REGEXP in string notation in the result.

*** The features `md5' and `overlay' are now provided by default.
*** The special form `save-restriction' now works correctly even if the
