It expects to read an Oberon Text file from STDIN and outputs to STDOUT.
Without any options it will write pseudo-XML which contains all information gathered from the Text file. By adding the -nopos Option the pos-Attribute will be suppressed. This form is better suited when you want compare the output with some other file.
With the -plain Option a plain Ascii file is created, stripped of all formatting and with the Oberon end of line character CR converted to NL. Ctrl-Chars except TAB are stripped too.
