Fully supported commands are:
CATALOG , CDTEXTFILE , FLAGS , INDEX , ISRC , PERFORMER ,
POSTGAP , PREGAP , REM , SONGWRITER , TITLE
Further supported commands introduced by cdrecord (usage like PERFORMER):
ARRANGER , COMPOSER , MESSAGE
Partly supported commands are:
FILE which supports only types BINARY , MOTOROLA , WAVE
TRACK which supports only datatypes AUDIO , MODE1/2048
Unsupported types of FILE or TRACK lead to failure of the call.
libburn does not yet support mixing of AUDIO and MODE1/2048. So this call
will fail if such a mix is found.
Empty lines and lines which start by '#' are ignored.
@param session Session where to attach tracks. It must not yet have
tracks or else this call will fail.
@param path Filesystem address of the CDRWIN cue sheet file.
