- Note: A version 2 tag will NOT be added unless one of the input fields
- won't fit in a version 1 tag (e.g. the title string is longer than 30
- characters), or the '--add-id3v2' or '--id3v2-only' options are used,
- or output is redirected to stdout.
- MS-Windows-specific options:
- --priority <type> sets the process priority:
- 0,1 = Low priority (IDLE_PRIORITY_CLASS)
- 2 = normal priority (NORMAL_PRIORITY_CLASS, default)
- 3,4 = High priority (HIGH_PRIORITY_CLASS))
- Note: Calling '--priority' without a parameter will select priority 0.
