  10 (* The full type ClientCommand.command refers to environment types in
  11  * other client modules like ClientStart.env, ClientBuild.env, etc. If
  12  * we want to do logging from, e.g. inside ClientBuild, then the fact
  13  * that EventLogger's logging functions take the current client
  14  * command as an argument, this creates a circular dependency
  15  *
  16  * ClientBuild -> EventLogger -> ClientCommand
  17  *      ^-------------------------------v
  18  *
  19  * To avoid this, we have here a stripped-down version of
  20  * ClientCommand.command where the data carried by each branch is only
  21  * the data required for logging. *)
