[antlr-interest] getting started with antlr

The -jar parameter is used for executable jars only. The manifest of an 
executable jar file tells Java the Main class. As antlr-3.0.1.jar is not 
an executable jar file, there is no Main class entry in its manifest.

Are you sure?

This is what I use for conversion (Windows style, I think you have to 
use colons instead of semicolons in unix):
java -cp 
libs/antlr-2.7.7.jar;libs/antlr-3.0.1.jar;libs/stringtemplate-3.1b1.jar; 
org.antlr.Tool T.g
