-- An ACE file defines the environment for a project, together with its root
-- class and initial creation procedure.
--
-- ACE is an abbreviation of Assembly of Classes in Eiffel.
--
-- Use of an ACE file obviates the need for specifying many options on the
-- command line and ensures consistency between successive compilations or
-- other operations on the project. Such consistency makes it easier to test
-- and debug, since changes from one compilation to the next are guaranteed to
-- be limited to coding changes rather than to changes in the compilation
-- environment.
--
-- To launch the compilation with this ACE file, just type:
--
--               compile example1.ace
--
-- This is a very simple example with the most basic ACE file.

system
       -- The system section is introduced by the keyword system followed by
       -- the name to be given to the executable program which will be produced
       -- by a compilation. The system name should be enclosed in double
       -- quotes.
   "hello"

root
       -- The root section defines the root class of the system and the initial
       -- creation procedure. The creation procedure is the routine which is
       -- executed first when the executable program is run; it is equivalent
       -- to main() in a C program. This procedure must be a procedure in the
       -- root class and must be declared as a creation procedure in that
       -- class.
   HELLO_WORLD: main

cluster
       -- The cluster section is introduced by the keyword cluster and defines
       -- an ordered list of clusters. Roughly speaking, a cluster can be
       -- considered as a directory in which Eiffel source files are to be
       -- searched for. The order of this list of clusters is important because
       -- clusters are considered sequentially when searching for an Eiffel
       -- source file. The first class file found in the search is the one that
       -- will be used.  Also note that one may only use the / character as the
       -- directory separator.
   "${path_tutorial}"
   "${path_liberty_core}/loadpath.se"
