|The s/// is a sub(/\s*#.*/, '').

.....and I said:

|
|line.gsub!(/\s*#.*/, '')
|next if (line =~ /^$/)
|
|Now, what's this do:
|
|next if line.comment?
|
|See?

Another even better idea!!!!

def class ConfigFile
   def each_line
      .... read line until non-comment, and strip comments out...
   end
end

Now to go off and do it...
