The profile dump sub-command supports a couple of useful flags:

//
// Non-canonical values will still parse as long as they are well formed,
// but will be re-emitted in their canonical form. (So always use canonical
// form, or don't diff.)
//
// This format is intended to make it difficult to use these numbers without
// writing some sort of special handling code in the hopes that that will
// cause implementors to also use a fixed point implementation.
//

- [manifest](../operator/cmd/mesh/manifest.go): the manifest subcommand is used to generate, install, diff or migrate Istio manifests, it has the following subcommands:
    - [install](../operator/cmd/mesh/install.go): the install subcommand is used to generate an Istio install manifest and apply it to a cluster.
    - [diff](../operator/cmd/mesh/manifest-diff.go): the diff subcommand is used to compare manifest from two files or directories.
