Hi,
 From what I see, basic_path will with < std::string, path_traits > ( 
from path.hpp). I'm deriving from basic_path and using that constructor.
This line 'looks' to work fine for path:
typedef basic_path< std::string, path_traits > path;

But I get the error:
  'basic_vpath<String,Traits>::basic_vpath(const 
basic_vpath<String,Traits> &)' : cannot convert parameter 1 from 
'CString' to 'const basic_vpath<String,Traits> &'

When I add my extension above. I'd like this vpath class to have all the 
functionallity of path. The added stuff would kick in on a signature of 
$(..) in the path.

Best, Dan.
