A few suggestions, if I may.

I wonder if your option detection might be more efficient as:

trace = true if ARGV.include? "-t"
dump  = true if ARGV.include? "-d"
filenames = ARGV.delete_if { |n| n !~ /^[^-]/ }
fn = filenames.empty? ? nil : filenames.first

It would save you from looping through ARGV, just in case it's a mile 
long or something.  :-)
