public class Compile
extends LLkParser
implements metalTokenTypes
This class is automatically generated by the antlr tool from the file metal.g. It compiles a metal file and generates a file formalism.java , that is in the packacke lang.language_name . To run the compiler just call 
 java aioli.metal.Compile file.metal
A metal specification starts with formalism of language_name is and ends with end . The body is composed of a list of declarations separated by semi colons. The possible declarations of operator are for star and plus list operators, fixed operatorm nullary operator, string atomic operator, integer atomic operator. They correspond to the different declaration: 
env_list -> ENV * ...;
exp_list -> EXP + ...;
bin ->  EXP EXP ;
null -> ;
var -> implemented as STRING;
int -> implemented as INTEGER;
Phyla are presented as capital letters. A declaration enumarates the elements that a phylum includes (operators and phyla) 
BEXP := int var;
EXP :=  bin null BEXP;
Finally here is the complete definition of the toy language 
formalism of toy is
TOP  ::= null1 null2 app var abs tlist ;
null1  -> ;
null2  -> ;
app  -> TOP TOP ;
abs  -> TOP TOP ;
var  -> implemented as STRING ;
tlist  -> TOP * ... ;
end
