DITA2Go uses the DCL (Document Coding Language) filter to convert XML files according to settings you have already specified in a configuration file (and optionally as arguments to the DCL command). Before you can convert files this way, you must set up a configuration file for the conversion; see §2. Converting DITA documents.
When your configuration file is ready, you run the DITA2Go DCL filter at a command-line prompt in a command window.
You will also need to use the full path to the DITA2Go version of dcl.exe on the command line; see §2.7.1 Executing the correct version of DCL.
