//-----
// C++ does not provide a regular expression feature as standard.
//
// To run this code you will need to first download and install
// the PCRE library from http://www.pcre.org/ and 
// the PME library from ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib/
// 
// Note that on Linux systems PCRE is often already installed in /usr/lib/libpcre* or /usr/local/lib/libpcre*. 
//
// Compile and run on Unix using 
// # c++ x.cpp -lpme -lpcre 
// # ./a.out
