I see a file that is downloadable (syntax.rb) on the RAA link,  but 
there are no downloadable files at the grammar page on RubyForge.  Will 
you be releasing an update soon?

How close is it to EBNF?  I'm interested in doing a VHDL parser - how much 
tweaking would I need to do to the VHDL EBNF to get something working?


After we've got Verilog and VHDL parsers working would anyone be 
interested in a RubySynthesis package?  Maybe verification?  Or perhaps 
more realistically just translation between VHDL <-> Verilog?  An 
automatic testbench generator would be nice (and certainly doable) as 
well.
