a regexp is a very powerful operation. This section explains how to write
regexps; the following section says how to search for them.
+ @findex re-builder
+ @cindex authoring regular expressions
+ For convenient interactive development of regular expressions, you
+ can use the @kbd{M-x re-builder} command. It provides a convenient
+ interface for creating regular expressions, by giving immediate visual
+ feedback in a separate buffer. As you edit the regexp, all its
+ matches in the target buffer are highlighted. Each parenthesized
+ sub-expression of the regexp is shown in a distinct face, which makes
+ it easier to verify even very complex regexps.
