it gets to be seen by the regular expression engine, consequently it gets to be seen by the regular expression engine, consequently
escapes in regular expressions have to be doubled up when escapes in regular expressions have to be doubled up when

assume that your compiler supports Koenig lookup, if yours
doesn't (for example VC6), then you will have to add some boost::
prefixes to some of the function calls in the examples.</p>
