In v2, you just manually request a template for, say, assignment and  
stuff it with values.  Either return or spit out that template's  
output.  In v3, it's a bit easier but the same process:

tree grammar T;
options { output=template; }
...
assign : ID '=' expr -> assigntemplate(lhs={$ID.text}, rhs= 
{$expr.template}) ;

In this case, assign returns a template.  [actually, the $ID.text is  
broken in the tree parser for v3 at the moment, but that is my  
intention].  The assigntemplate is defined somewhere in a group file.
