+ (description "@code{pcre2el} or @code{rxt} (RegeXp Translator or RegeXp
+Tools) is a utility for working with regular expressions in Emacs, based on a
+recursive-descent parser for regexp syntax. In addition to converting (a
+subset of) PCRE syntax into its Emacs equivalent, it can do the following:
+
address@hidden
address@hidden convert Emacs syntax to PCRE
address@hidden convert either syntax to @code{rx}, an S-expression based regexp
syntax
address@hidden untangle complex regexps by showing the parse tree in @code{rx}
form and
+highlighting the corresponding chunks of code
address@hidden show the complete list of strings (productions) matching a
regexp,
+provided the list is finite
address@hidden provide live font-locking of regexp syntax (so far only for Elisp
+buffers – other modes on the TODO list).
