SAS Document Conversion
Server is a helper service that extracts plain text from file formats
so that the text can be analyzed by SAS Text Miner. File formats include
PDF, Microsoft Office (DOC, DOCX, PPT, PPTX, XLS, XLSX), OpenOffice.org
(ODT, ODP, ODS), and RTF. By default, the Text Import node
and the %TMFILTER macro communicate with SAS Document Conversion Server
on TCP port 7111.
