Ann: HAC v.0.1

[Gautier write-only address <gautier_niouzes@hotmail.com>]

HAC (HAC Ada Compiler) is a quick, small, open-source Ada
compiler, covering a subset of the Ada language.
HAC is itself fully programmed in Ada.

Web site: http://hacadacompiler.sf.net/
From there, links to sources and an executable for Windows.

Source repositories:
  #1 svn: https://sf.net/p/hacadacompiler/code/HEAD/tree/trunk/
  #2 git: https://github.com/zertovitch/hac

* Main improvements since v.0.0996:

  - packages and subpackages are now supported
  - modularity: packages and subprograms can be standalone
      library units, stored in individual files with
      GNAT's naming convention, and accessed from other units
      via the WITH clause
  - validity checks were added for a better detection of
      uninitialized variables.

Package examples and modularity tests have been added.
Particularly, a new PDF producer package with a few demos
is located in the ./exm/pdf directory.

Enjoy!
