Most of the changes required when installing an application can be accomplished by providing the appropriate plug-ins. However, some of the configuration files used by the Lotus® Expeditor platform may need to be updated.
Changes to these files can be made either by installation programs, or by using an Install Handler associated with the application Feature being installed. An Install Handler is invoked at certain checkpoints within the installation process. During the applicable checkpoints, code provided within the Install Handler can make the required changes to the configuration files.
