-/// Simple command to analyse disk usage from the terminal
-///
-/// Usage:
-///  btrfs-sync [options] <src> [<src>...] [[user@]host:]<dir>
-///
-///  -k|--keep NUM     keep only last <NUM> sync'ed snapshots
-///  -d|--delete       delete snapshots in <dst> that don't exist in <src>
-///  -z|--xz           use xz     compression. Saves bandwidth, but uses one CPU
-///  -Z|--pbzip2       use pbzip2 compression. Saves bandwidth, but uses all CPUs
-///  -q|--quiet        don't display progress
-///  -v|--verbose      display more information
-///  -h|--help         show usage
-///
-/// <src> can either be a single snapshot, or a folder containing snapshots
-/// <user> requires privileged permissions at <host> for the 'btrfs' command
-///
-/// Cron example: daily synchronization over the internet, keep only last 50
-///
-/// cat > /etc/cron.daily/btrfs-sync <<EOF
-/// #!/bin/bash
-/// /usr/local/sbin/btrfs-sync -q -k50 -z /home user@host:/path/to/snaps
-/// EOF
-/// chmod +x /etc/cron.daily/btrfs-sync
