XPCNativeWrapper in Firefox versions prior to 1.1

In Firefox versions prior to 1.1, use of XPCNativeWrapper requires manually constructing an XPCNativeWrapper and passing it the object to be wrapped and the names of the methods/properties to be exposed as arguments. The resulting object exposes ONLY the methods/properties whose methods were passed as arguments. This is described in more detail in the the entry for XPCNativeWrapper at the MozillaZine KnowledgeBase.
