An AutoIt script can be converted into a stand-alone executable. This can be run on computers that do not have the AutoIt interpreter installed. A wide range of function libraries are available. They are known as UDFs, or "User Defined Functions". Some are included as standard. Others are available from the website. They add extra abilities to the language. AutoIt has a special editor, an Integrated development environment or IDE. It is based on the free SciTE editor. The compiler and help text are included in this special editor and provide a standard environment for developers.
