[antlr-interest] Java Target - How to Generate the Parser and Lexer at Runtime?

[Sameh W. Zaky]

Dear Brat,

You're right..

But now I need to change my question because I found out that Parser.java
generated from this action is different than Parser.java generated when I
click 'Run..' in ANTLRWorks and give it an input text..

So my new question is: How, from the command line, do I run the grammar
(giving it an input text file, let's say)?
