package System.Garlic is

   pragma Pure;

   --  GARLIC is organized around several modules, which form a coherent
   --  set:
   --    System.Garlic
   --       This is the top-level package for all the PCS.
   --    System.Garlic.Protocols
   --       This package defines the Protocol_Type type and its primitive
   --       operations. An instance of Protocol_Type'Class defines a
   --       communication mean (e.g. Tcp) and performs some basic operations.
   --    System.Garlic.Options
   --       This package gets the Boot_Location and other informations from
   --       the command line.
   --    System.Garlic.Startup
   --       This package 'withes' the different protocols to link them into
   --       the runtime and do the job of registering them. It also offers
   --       services to initialize the PCS.
   --    System.Garlic.Physical_Location
   --       This package defines a Location type which will represents the
   --       way to use to find a protocol. This type is usable for
   --       inter-partitions communications and will be used to spread
   --       the knowledge into the PCS.
   --    System.Garlic.Heart
   --       This is the heart of the system. It defines callable operations
   --       to initialize the system and send Params_Stream_Type instances
   --       accross partitions, and thus may be called by System.RPC to
   --       perform the remote calls.
   --    System.Garlic.Remote
   --       This package provides the necessary procedures needed to launch
   --       the slave partitions with the right options.
   --    System.Garlic.Replay
   --       This package provides the user with facilities to record and
   --       replay the execution of a distributed program.
   --    System.Garlic.Filters
   --       This package implements data filtering.

   Communication_Error : exception;
