\fB\-show_stream\fR iso_rr_path [***]
Display the content stream chain of data files in the ISO image. The chain
consists of the iso_rr_name and one or more streams, separated by " < " marks.
A stream consists of one or more texts in ''-quotation marks, eventually
separated by "." characters. The first text describes the stream type,
the following ones describe its individual properties.
Frequently used types are:
.br
'disk'.'disk_path' for local filesystem objects.
.br
'image'.'iso_rr_path' for ISO image file objects.
.br
'cout'.'disk_path offset count' for -cut_out files.
.br
'extf'.'filter_name' for external filters.
