4	# with this script you can compress the VOID into a file of N gb.
5	# It first compresses the file `null' using bzip2, then it compresses the .bz2
6	# file using gzip, then using rar, finally using zip.
7	# The whole process is reiterated `N+1'# times.
8	#
9	# Launch this script as follow in a temporary directory:
10	# mkdir temp_dir
11	# cp bznull.sh temp_dir/
12	# cd temp_dir/
13	# ./bznull.sh 5 > /dev/null
14	#
15	# If the first argument to bznull.sh is `N', the number of iteration.
