When a plug-in step finishes processing, its default post-processing element is executed. The post-processing element is defined in the plug-in's XML definition, see the section called “Creating Plug-ins”
You can override the default behavior by entering your own script into the step's Post Processing Script field. A post-processing
script can contain any valid JavaScript code. Although not required, it's recommended that scripts be wrapped in a CDATA
element.
See the section called “The <post-processing>
Element” for more information.
