package Gnatstub.Sampler is

   procedure Brief_Help;
   --  Prints brief help information to stdout.

   procedure Initialize;
   --  Reads and checks the command line parameters and initializes the
   --  Gnatstub options. Checks the existence of the files to be processed
   --  by Gnatstub and applicability of the gnatstub options with these files.
   --  Tries to create the tree file, if necessary.
   --  If everything is OK, sets the global Is_Initialized variable True.
   --  This procedure does not use anything from ASIS

   procedure Put_Gnatstub_Version;
   --  outputs the gnatstub version information

   procedure Create_Sample;
   --  If Is_Initialized, generates the sample body. This procedure is an
   --  ASIS application

   procedure Clean_Up;
   --  Now the only thing it does is removing the tree file, if needed
