simple converter from OpenDocument Text to plain text

 odt2txt is a command-line tool which extracts the text out of OpenDocument
 Texts, as produced by OpenOffice.org, KOffice, StarOffice and others.
 .
 odt2txt can also extract text from some file formats similar to OpenDocument
 Text, such as OpenOffice.org XML (*.sxw), which was used by OpenOffice.org
 version 1.x and older StarOffice versions. To a lesser extend, odt2txt may
 be useful to extract content from OpenDocument spreadsheets (*.ods) and
 OpenDocument presentations (*.odp).
 .
 It is small and fast, can output the document in many encodings and
 adopts to your locale.
