== Introduction ==
XPIDL stands for XP Interface Description Language. It is a specification for XPCOM which is a cross platform adapter description language. An adapter description language is used to describe an adapter which unrelated with its machine language. The description of the adapter can use specialized tools to handle automatoc automatic generation of language that is unrelated to the adapter's specifications. Typically XPIDL is frequently used to generate C++ header files and typelib information.

=== Interfaces ===
interface nsToolbar {
};
};
C++ get and set methods for attributes are automatically declared for attributes in the
interface. For example attribute name foo generates accessor methods GetFoo and SetFoo.

=== Include Terminology ===
To referencing interfaces defined in other files, you must type #include "filename.idl".
In XPIDL, #include only includes the file once, so the #include statement does not need the ifdefs which will be neede with required for the
the C preprocessor.
const float invalid_constant = 6.0; Warning: const decl 'invalid_constant' was not of type short or long, ignored
