val create_empty_switch : 
  OpamStateTypes.rw OpamStateTypes.global_state ->
  ?synopsis:string ->
  ?repos:OpamTypes.repository_name list ->
  ?invariant:OpamTypes.formula ->
  OpamTypes.switch ->
  OpamStateTypes.rw OpamStateTypes.global_state

Initialises a new switch with the given name in the given opam root, registers it in the global config and returns the updated global state

val write_selections : OpamStateTypes.rw OpamStateTypes.switch_state -> unit

Writes the current state file to disk (installed, pinned, root packages etc.). Unless OpamStateConfig.(!r.dryrun)

val set_current_switch : 
  OpamStateTypes.rw OpamStateTypes.global_state ->
  'a OpamStateTypes.switch_state ->
  'a OpamStateTypes.switch_state

Updates the global default switch to the one corresponding to the given state; fails and exits with a message if the switch is external

val gen_switch_config : 
  OpamTypes.dirname ->
  ?synopsis:string ->
  ?repos:OpamTypes.repository_name list ->
  ?invariant:OpamTypes.formula ->
  OpamTypes.switch ->
  OpamFile.Switch_config.t

Create the default global_config structure for a switch, including default prefix

val install_switch_config : 
  OpamTypes.dirname ->
  OpamTypes.switch ->
  OpamFile.Switch_config.t ->
  unit

(Re-)install the configuration for a given root and switch

val install_metadata : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.package ->
  unit

Add the package metadata to the switch-local cache of installed packages

val remove_metadata : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.package_set ->
  unit

Remove the metadata of the package from the switch-local cache of installed packages

val add_to_reinstall : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  unpinned_only:bool ->
  OpamTypes.package_set ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Update the on-disk set of packages marked to reinstall on the current switch (excepting compiler packages, and pinned packages if unpinned_only is set)

val add_to_installed : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  ?root:bool ->
  OpamTypes.package ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Updates the package selections and switch config to take into account the given newly installed package. The updated state is written to disk unless OpamStateConfig.(!r.dry_run) and returned.

val remove_from_installed : 
  ?keep_as_root:bool ->
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.package ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Updates the package selections and switch config to take into account the removed package. The updated state is written to disk unless OpamStateConfig.(!r.dry_run), and returned. If keep_as_root, the package isn't removed from the switch state installed_roots set.

val update_switch_state : 
  ?installed:OpamTypes.package_set ->
  ?installed_roots:OpamTypes.package_set ->
  ?reinstall:OpamTypes.package_set ->
  ?pinned:OpamTypes.package_set ->
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Update the switch selections with the supplied optional arguments. Changes are written to disk and returned
