.SH DESCRIPTION
.B jcat
shows the contents of a journal block in the file system journal.  The 
inode address of the journal can be given or the default location will
be used.  Note that the block address is a journal block address and not
a file system block.  The raw output is given to STDOUT.

Use '\-f list' to list the supported file system types.
If not given, autodetection methods are used.

.IP "-o imgoffset"
The sector offset where the file system starts in the image.  
.IP "-b dev_sector_size"
The size, in bytes, of the underlying device sectors.  If not given, the value in the image format is used (if it exists) or 512-bytes is assumed.
.IP -V
Display version
.IP -v
verbose output
.IP "image [images]"
The disk or partition image to read, whose format is given with '\-i'.
Multiple image file names can be given if the image is split into multiple segments.
If only one image file is given, and its name is the first in a sequence (e.g., as indicated by ending in '.001'), subsequent image segments will be included automatically.
.IP [inode]
The inode where the file system journal can be found. 

.IP jblk
