// zrepl replicates ZFS filesystems & volumes between pools

// Code Organization
//
// The cmd package uses github.com/spf13/cobra for its CLI.
//
// It combines the other packages in the zrepl project to implement zrepl functionality.
//
// Each subcommand's code is in the corresponding *.go file.
// All other *.go files contain code shared by the subcommands.
