[Boost-users] string boost::split

Hello! For example I want to split string with single char '\t' delimeter. According to docs this can be done this way: std::vectorstd::string options; std::string sep; sep += '\t'; boost::split(options, line, boost::is_any_of(sep)); But if I want to use double tab as a delimiter? Is there an alternative to boost::is_any_of like "boost::just_what_i_say"
