Usage: nomad acl token create [options]

  Create is used to issue new ACL tokens. Requires a management token.

General Options:

  ` + generalOptionsUsage() + `

Create Options:

  -name=""
    Sets the human readable name for the ACL token.

  -type="client"
    Sets the type of token. Must be one of "client" (default), or "management".

  -global=false
    Toggles the global mode of the token. Global tokens are replicated to all regions.

  -policy=""
    Specifies a policy to associate with the token. Can be specified multiple times,
    but only with client type tokens.
