ODT2Txt.exe,  Version 1.00
Return plain text content of an OpenOffice file without requiring OpenOffice

Usage:    ODT2Txt.exe  odtfile  [ encoding | /D ]

or:       ODT2Txt.exe  /E

Where:    odtfile      is the path of the OpenOffice file to be read
                       (no wildcards, only .odt extension allowed)
          encoding     is the output encoding, e.g. UTF-8 to preserve
                       Unicode characters, or IBM437 to convert Unicode
                       doublequotes to ASCII
         /D            use the encoding specified in the document file
         /E            list all available encodings

Notes:   If the specified encoding does not match any available encoding
         name, the program will try again, ignoring dashes; if that does
         not provide a match, the program will try matching the specified
         encoding with the available encodings' codepages.
         This program requires .NET 4.5.
         Return code ("errorlevel") 1 in case of errors, 0 on success.
