* BRICC

** Usage

$ ./bricc.rb -h
Usage: ./bricc.rb [options] file
    -h, --help                       Displays this information
    -V, --version                    Print version
    -t, --target TARGET              Transformation target [rtt|ros]
    -v, --verbose                    More verbose output
    -o, --outdir DIR                 Output directory
    -p, --params a,b=x,c             List of target specific parameters


** Model files

   IMPORTANT:

   you can use arbitrary Ruby expressions in the model file to read
   codels from other files etc, but it is important that the actual
   model enclosed in "RGen::ModelBuilder.build(Bcm) do [...] end" is
   the *last* statement in the file.

   See 'ex_publisher.rb' and 'ex_subscriber.rb' in examples.


** Internals

*** Files

    bricc.rb:
	 briccs component compiler, reads model and

    bcm-regen.rb:
	 the current metamodel (generated from the Eclipse Ecore
	 model, so don't edit directly)

    bcm-codel-ext.rb
	 toplevel codel parsing

    bcm-codel-ros.rb
    bcm-codel-rtt.rb
   	 conversion of bcm_operations to target specific operations

   templates/
	 code generation templates

   tt/
	 PEG grammer used for codel parser generation

    rgen2ecore.rb, ecore2rgen.rb, regenerate.sh
	 helper tools for converting metamodels from the Eclipse version


*** Creating a new target

    For creating a new target "foo" you will need to:

       1) add the "foo" target to the toplevel bricc.rb option
	  handling and to the code generator call.

       2) add a "dispatching" template to templates/Root.tpl

       3) create a new target subdirectory templates/foo

       4) implement appropriate templates to generate your target
