The utility not required the M or Z values in geometry. The results can be stored in any OGR supported format. Also some information writed to the stdout.</p> <dl> <dt><b>–help-general</b>:</dt> <dd>Show the usage. </dd> <dt><b>-progress</b>:</dt> <dd>Show progress. </dd> <dt><b>-quiet</b>:</dt> <dd>Supress all messages except errors and results. </dd> <dt><b>-f</b> <em>format_name</em>:</dt> <dd>Select an output format name.
