# Configuration

The document processing tools are set up as launch configurations of the category External Tools. There are different configuration types for different document types. For example there is a configuration type for Sweave (LaTeX+R) and another type for Wikitext+R documents. The options available for each type may vary slightly.

A tool configuration is usually an assembly of processing steps, for example 'Preprocessing' and 'Produce Output' and a Preview step. Each step can be configured to execute an operation. When running the configuration, the enabled step operations are run successively.

## Main Tab

The working directory specifies the local working directory for the tool configuration. Among others that directory is used in the steps:

- to resolve relative resource path definitions, and
- as working directory for all operations (if not specified otherwise).

## Step Tabs

When enable in complete run is checked, the step is executed when running the complete configuration. The option is ignored when a single step is executed by the appropriate action.
