How can I allow single-line comments with EOF on the end instead of a newline?

Terence Parr Here is a simple example that works for me.
class CL extends Lexer;
options {
charVocabulary = 'u0000'..'u007f';
}
{
public static void main(String[] args) throws Exception {
CL lexer = new CL(System.in);
Token t = lexer.nextToken();
System.out.println("Token: "+t);
while ( t.getType()!=Token.EOF_TYPE ) {
System.out.println("Token: "+t);
t = lexer.nextToken();
}
}
}
ID : ( 'a'..'z')+;
WS : ' ' | '
' ;
CMT : "//" (~'
')* ('
')? ;
