var Cmd = &charm.Spec{
	Name:  "manage",
	Usage: "manage",
	Short: "run compaction and other maintenance tasks on a lake",
	Long: `
The manage command performs maintenance tasks on a lake.

Currently the only supported task is compaction, which reduces
fragmentation by reading data objects in a pool and writing their
contents back to large, non-overlapping objects.

If the -monitor option is specified and the lake is located via network
connection, zed manage will run continuously and perform updates as
needed. By default a check is performed once per minute to determine if
updates are necessary. The -interval option may be used to specify an
alternate check frequency in duration format.

If -monitor is not specified, a single maintenance pass is performed on
the lake.

The output from manage provides a per-pool summary of the maintenance
performed, including a count of objects_compacted.

As an alternative to running manage as a separate command, the -manage
option is also available on the "zed serve" command to have maintenance
tasks run at the specified interval by the service process.
