Something like:

   procedure Do_Something_With (Item : String; Index : Positive;
Quit : in out Boolean);
   -- processes the file named Item.  Implementation left to the
reader.

   procedure Do_Something_On_All_Files_Matching is
     new GNAT.Directory_Operations.Iteration.Find (Action =>
Do_Something_With);
begin
   Do_Something_On_All_Files_Matching (Root_Directory => "/",
File_Pattern => ".*\.ad[bs]");
