Regular expression support, which is an optional Ceylan feature. To analyze a string, construct a RegExp object.

 RegExp re( "www.host.com" ) ;
 if ( re.matches( aPattern ) ) ...

No RegExp instance will be created if the feature for regular expression support is not available, since the RegExp will fail in this case.

Tcl regular expression (man re_syntax) to learn the pattern-matching syntax.
