Compiler Frontend Project

Use the Eli system to write a frontend for the TassKaf subset 
of Java.  Initially, your frontend should focus upon distinguishing 
correct and incorrect code.  In its final form, it will build a symbol 
table and create as its output an abstract syntax tree of the TassKof 
source program.

Your generated lexical scanner should be able to identify comments.  
Your generated parser should be able to perform syntax analysis and 
error detection (and recovery).  Your semantic analyzer, written
as an attribute grammar, should supply all the fields of the
abstract syntax tree necessary for code generation.

Test your frontend on the TassKaf code samples.

To use the Eli system, add the following to your path (preferably 
towards the beginning, prior to /usr/lang):

  /usr/unsupported/installers/lewis/eli/elisys/bin

Run the script "eli" ...
