.SH NAME
compress_gcloop_ucl \- creates gcloop_ucl images [PLACEHOLDER]
.SH SYNOPSIS
.B compress_gcloop_ucl [options] infile outfile
.B compress_gcloop_ucl -V
.SH DESCRIPTION
\fBcompress_gcloop_ucl\fR can be utilized to create a 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
.SH OPTIONS
.TP
.BR -b 
Set the 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
.BR -c
Set the compression level, the range is up to the compressor used
commonly 0-10 for ucl algorithm and 0-9 for zlib algorithm.
.TP
.BR -i
Set the input imagesize, in bytes. To be used if cannot be determined
.TP
.BR -I
Force the input imagesize, in bytes.
.TP
.BR -v
Verboseness level, cumulable. -v just give you a summary, -vv and -vvv
report per block statistics.
.TP
.BR -V
Print the version and exit.
.TP
.BR -C
\&[not implemented yet]
Set the compression algorithm.
