Pipeline Variables
This module serves for setting values global to the complete processing pipeline.
It is the key to making a pipeline setup independent from its actual location on a user's computer, as it allows defining and referencing resources relatively to the location of the pipeline document.
Apart from setting up pre-defined pipeline variables used by the default modules supplied, you can also set custom variables that are accessible e.g. from the UPL module. It also allows defining variables that will later be passed in dynamically, e.g. when using the Java source export.
