.SH NAME
create_gcloop_ucl \- creates gcloop_ucl images
.SH SYNOPSIS
.B create_gcloop_ucl [options] infile blocksize > outfile
.B create_gcloop_ucl -V
.SH DESCRIPTION
\fBcreate_gcloop_ucl\fR can be utilized to create an ucl compressed 
image to be used as compressed loopback.

.SH PARAMETERS
.TP
.BR infile
Input image file, to use stdin instead use "-" instead of a filename
.TP
.BR outfile
Output file
.TP
.BR blocksize
Blocksize in bytes. The number has to be a multiple of 512.The 
suggested sizes are 65536 (64k) and 131072 (128k). Due to kernel
memory allocation 128k is the current max
.TP
.SH OPTIONS
.TP
.BR -c
\&[not implemented yet] 
Set the compression level, the range is up to the compressor used
