Install the CMOD Server package on your system - no need to configure CMOD, you just want access to the arsdoc tool.
From inside the CMOD Client, create a *Public* Named Query for the documents you want to retrieve, but make sure the name you use doesn't have any spaces or other special characters in it, just letters and numbers.
Use the "arsdoc get" -q option to specify the named query from the step above to retrieve them.
