[antlr-interest] Mark/rewind documentation

[Xavier Décoret]

In a recent thread about rewinding a token, the mark/rewind mechanism 
was mentionned. I am looking in the manual and I cannot find that much 
info about this mechanism. There is just an example of mark/rewind calls 
just before section "Scanning binary files" in    
http://www.antlr.org/doc/lexer.html#Lexical_Analysis_with_ANTLR.

Where can I find more info?

What I want to do is multiplexing with rewinding of a token. When lexer0 
finds a @, it switch the selector to another lexer (lexer1, which shares 
the same input) *and* rewind the @ because it must be used by lexer1.
