path matching problem

[Charles Hixson]

Is there a better way to do this?  (I want to find files that match any 
of some extensions and don't match any of several other strings, or are 
not in some directories.):

  import	std.file;

...

  string  exts  =  "*.{txt,utf8,utf-8,TXT,UTF8,UTF-8}";
  string[]  exclude  =  ["/template/",  "biblio.txt",  "categories.txt",
         "subjects.txt",  "/toCDROM/"]

  int  limit  =  1
  //  Iterate  a  directory  in  depth
  foreach  (string  name;  dirEntries(sDir,  exts,  SpanMode.depth))
  {  bool  excl  =  false;
     foreach  (string  part;  exclude)
     {  if  (part  in  name)
        {  excl  =  true;
           break;
        }
     }
     if  (excl)  break;
etc.
