-- collaboration between Software Engineering Laboratory of the Swiss --
-- Federal Institute of Technology in Lausanne, Switzerland, and the --
-- Scientific Research Computer Center of the Moscow State University, --
-- Russia. This work was supported by a grant from the Swiss National --
-- Science Foundation, no 7SUPJ048247, funding a project "Development of --
-- ASIS for GNAT with industry quality". --
-- --
-- Gnatstub is now maintained by AdaCore (http://www.adacore.com). --

pragma Ada_2012;
-- This package defines routines providing the main functionality of
-- Gnatstub.
with Asis; use Asis;
package Gnatstub.Sampler is
procedure Brief_Help;
-- Prints brief help information to stdout.
procedure Print_Gnatstub_Usage;
-- Similar to Brief_Help, but corresponds to the general format generated
-- by other GNAT tools for '--help' option, and sends the output into
-- 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 Create_Sample;
-- If Is_Initialized, generates the sample body. This procedure is an
-- ASIS application
procedure Clean_Up;
-- Beacuse of historical reasons, the clean-up procedure for gnatstub
-- differs from the standard clean-up procedure for othet AdaCore ASIS
-- tools that are based on ASIS UL. gnatstub creates the tree file in the
-- current directory and it may reuse the existing tree file and it may
-- keep the tree file it has created. So this procedure first removes the
-- tree file in the current directory (if the option that keeps the tree
-- is not specified), and then it calls the standard clean-up procedure to
-- clean the temporarty directory (if it has been created as a part of
-- project file processing).
