 using namespace std;

 using boost::io::group;

 // ------------------------------------------------------------------------
 // Simple style of reordering :
 cout << format("%1% %2% %3% %2% %1% \n") % "o" % "oo" % "O";
 // prints "o oo O oo o \n"


 // ------------------------------------------------------------------------
 // Centered alignment : flag '='
 cout << format("_%|=6|_") % 1 << endl;
 // prints "_ 1 _" : 3 spaces are padded before, and 2 after.



 // ------------------------------------------------------------------------
 // Tabulations : "%|Nt|" => tabulation of N spaces.
 // "%|NTf|" => tabulation of N times the character <f>.
 // are useful when printing lines with several fields whose width can vary a lot
 // but we'd like to print some fields at the same place when possible :
 vector<string> names(1, "Marc-François Michel"), 
 surname(1,"Durand"), 
 tel(1, "+33 (0) 123 456 789");

 names.push_back("Jean"); 
 surname.push_back("de Lattre de Tassigny");
 tel.push_back("+33 (0) 987 654 321");

 for(unsigned int i=0; i<names.size(); ++i)
 cout << format("%1%, %2%, %|40t|%3%\n") % names[i] % surname[i] % tel[i];

 /* prints :


 Marc-François Michel, Durand, +33 (0) 123 456 789
 Jean, de Lattre de Tassigny, +33 (0) 987 654 321


 the same using width on each field lead to unnecessary too long lines,
 while 'Tabulations' insure a lower bound on the *sum* of widths,
 and that's often what we really want.
