Include directives

The IDL specification for a class normally contains #include statements that tell the SOM Compiler where to find the interface definitions (the .idl files) for:

• Each of the class's parent (direct base) classes, and
  
• The class's metaclass (if specified).

The #include statements must appear in the above order. For example, if class "C" has parents "foo" and "bar" and metaclass "meta", then file "C.idl" must begin with the following #include statements:

   #include <foo.idl>   #include <bar.idl>
   #include <meta.idl>

As in C and C++, if a filename is enclosed in angle brackets (< >), the search for the file will begin in system-specific locations. If the filename appears in double quotation marks (" "), the search for the file will begin in the current working directory, then move to the system-specific locations.
