	XPCOM - Wikipedia, the free encyclopedia
		XPCOM (Cross Platform Component Object Model) is a simple, cross platform component model similar to CORBA or Microsoft COM.
		On the developer side, XPCOM lets you to write components in C++, JavaScript, Python, or other languages for which special bindings have been created, and compile and run those components on dozens of different platforms, including these and others where Mozilla itself is supported.
		The flexibility to reuse the XPCOM components from the Gecko library and develop new components that run on different platforms facilitates rapid application development and results in an application that is more productive and easier to maintain.

	XPCOM Part 5: Implementation
		The purpose of XPCOM is to provide a mechanism for writing modular software objects called components over a large number of platforms.
		When the XPCOM component is destroyed, its implementation will call the smart pointer's destructor and properly release its reference to the other component.
		XPCOM includes a proxy manager that is able to examine the type information of an installed component to create a proxy interface that impersonates the component by capturing the parameters and passing them to the component in a thread-safe manner.

	XPCOM Part 1: An introduction to XPCOM
		XPCOM components can be written in C, C++, and JavaScript, and they can be used from C, C++, and JavaScript with extensions for Perl and Python that are under development (see Resources).
		XPCOM is tailored toward providing modular component support at the application level, so proxy services only support multiple threads sharing an otherwise non-reentrant component.
		Strictly speaking, XPCOM does not support remote objects like CORBA, but neither does XPCOM prevent you from writing a component that uses a socket or other means to talk to another component.

	Aggreg8.net: Philip Roche
		XPCOM (Cross Platform Component Object Model) and XPConnect (Cross Platform Connection to Components) are complementary technologies that enable the integration of external libraries with XUL applications.
		XPCOM components can be written in C, C++, and JavaScript, and they can be used from C, C++, JavaScript, Python, and with Perl extensions under development.
		XPCOM supplies a library of functions that allow to add/remove/edit elements in the RDF file and then save the altered data back to the file.

	XPCOM
		XPCOM can be difficult to master, but after reading this chapter, you should have a good sense of what it is and the important part it plays as Mozilla's core technology.
		XPCOM permits a reusable code module to be globally accessible to a Mozilla-based application.
		The key to the component architecture of XPCOM is the presence of binary-independent interface files that are used uniformly across platforms, languages, and programming environments.

	8.1 - XPCOM Interfaces
		In this section, we'll take a brief look at XPCOM (Cross-platform Component Object Model), which is the Object system that uses.
		XPCOM components are typically implemented natively, which means that they generally do things that JavaScript cannot do itself.
		The process of calling XPCOM from a script is called XPConnect, which is a layer which translates script objects into native objects.

	mozdev.org - plxpcom: docs/xpcom-perl
		XPCOM components implemented in Perl are created by writing Perl modules which define packages that allow for registering and loading an XPCOM component (or components), as well as the implementation of the component.
		The XPCOM perl package also comes with GenericModule and GenericFactory packages which can be used to implement the module and factory aspects of a component package quickly and easily.
		The first case is for allowing a perl object which implements an XPCOM interface to pass itself as an argument to another XPCOM method.

	Chapter 8: XPCOM
		The section "Creating a JavaScript XPCOM Component" lets you create an interface from start to finish-writing the implementation for that interface, compiling it into a type library, registering it with Mozilla, and then testing the new component.
		Above all, XPCOM is entirely open source, so there are no costs associated with it, no proprietary secrets in how it's put together, and you have various software licenses to choose from.
		Although XPCOM has become a solid framework, its developers are still making improvements and uncovering and fixing bugs.

		The purpose of XPCOM is to provide a mechanism for writing modular software objects (components) over a reasonably large number of platforms.
		As an example, I'm going to describe a fictional component that might be used to interface an XPCOM application to a Global Positioning Satellite receiver (or "GPS receiver" for short).
		A GPS receiver is an accessory we can attach to our computer to provide us with a few pieces of information: the current time, our position on the surface of the earth, and sometimes our elevation.
