remember that the escape is seen once by the C++ compiler, before
it gets to be seen by the regular expression engine, consequently
escapes in regular expressions have to be doubled up when
embedding them in C/C++ code.</p>
embedding them in C/C++ code. Also note that all the examples
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>
