[Boost-users] regex: seem to be missing something here

     fs::path upper("c:/differences", fs::native);
     fs::path checked(upper/"checked");

     assert(fs::exists(upper));
     assert(fs::exists(checked));

     fs::directory_iterator end;
     rg::regex rgx("*ps", rg::regex::basic);
     for (fs::directory_iterator it(upper); it != end; ++it)
     {
       if (rg::regex_match(it->string(), rgx))
         std::cout << "MATCH: ";
       else
         std::cout << "NOMATCH: ";
       std::cout << it->string() << std::endl;
     }

Supposed to be looking for ps files.  tried *\\.ps, which should work 
but also didn't.  Doesn't match any of the strings.

One example line of output:

NOMATCH: c:/differences/Adj. speed test case 5 (metric units).ps

Supposedly regex is greedy, no?  It should accept . as a * element and 
continue to match everything up to ps and ps also...why no worky?

Thanks.
