public class emit extends Object
Three classes are produced by this code:
Three parse tables are created as part of the parser class:
In addition to the method interface, this class maintains a series of public global variables and flags indicating how misc. parts of the code and other output is to be produced, and counting things such as number of conflicts detected (see the source code and public variables below for more details).
This class is "static" (contains only static data and methods).

Parameters: out stream to produce output on. act_tab the internal representation of the action table. compact_reduces do we use the most frequent reduce as default?
Parameters: out stream to produce output on. red_tab the internal representation of the reduce-goto table.
Parameters: out stream to produce output on. start_prod the start production of the grammar.
Parameters: out stream to produce output on.
Parameters: out stream to produce output on.
Parameters: out stream to produce output on. action_table internal representation of the action table. reduce_table internal representation of the reduce-goto table. start_st start state of the parse machine. start_prod start production of the grammar. compact_reduces do we use most frequent reduce as default? suppress_scanner should scanner be suppressed for compatibility?
Parameters: str string to prefix.
Parameters: out stream to produce output on. emit_non_terms do we emit constants for non terminals? sym_interface should we emit an interface, rather than a class?
