#define NEXGEN_FILTER_USAGE "[options] <xml-file>|<pkt-file> [...]\n\nImport audio from a Prophet NexGen system, using metadata contained in\none or more XML files.  Options are:\n\n--group=<group-name>\n     The Rivendell group to use.  This option is mandatory and has no default.\n\n--audio-dir=<path>\n     The full path to the directory containing the audio files.  This option\n     is ignored when importing PKT files, but mandatory for importing\n     using XML data.  It has no default.\n\n--reject-dir=<path>\n     The full path to the directory in which to place copies of XML files\n     which were unable to be processed.  Default is '/dev/null'.\n\n--cart-offset=<offset>\n     Apply integer <offset> to the NexGen cart number before importing.\n     Default is '0'.\n\n--delete-cuts\n     If the destination cart already exists, delete any existing cuts\n     within it before importing.\n\n--normalization-level=<level>\n     The level to use for normalizing the audio, in dBFS.  Specifying '0'\n     will turn off normalization.  Default is '0'.\n\n--verbose\n     Print status messages as files are processed.\n\n<xml-file> [..]\n     Filespec for XML file(s) containing import metadata.\n\n"
