[antlr-interest] empty right hand side

[Edwards, Waverly]

What would and empty right hand side look like in an ANTLR grammar?

While I've been desperately attempting to stand on my own two feet and
be able to determine a first and follow set from a grammar, I've read
and
have been told that determining these sets only become difficult when 
you have an empty production.  What would that look like?  It may sound
a bit silly but at no time have I ever seen an empty right-hand sides 
(conventionally written using the Greek letter epsilon) in an ANTLR
grammar.


Thank you very much for your time,
