(synopsis "Convert between PCRE, Emacs and rx regexp syntax")
(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:
@itemize
@item convert Emacs syntax to PCRE
@item convert either syntax to @code{rx}, an S-expression based regexp syntax
@item untangle complex regexps by showing the parse tree in @code{rx} form and
highlighting the corresponding chunks of code
@item show the complete list of strings (productions) matching a regexp,
provided the list is finite
@item provide live font-locking of regexp syntax (so far only for Elisp
buffers other modes on the TODO list).
@end itemize\n")
