  new to this myself so take that into consideration :wink:

basically i have a text file and i want my ruby class to perform a
regular expression to count the lines with a Tag in the text file

    ['--database', '-i', GetoptLong::REQUIRED_ARGUMENT]
  )
  opts.each do |opt, arg|
    case opt
      when '--style'
         require arg
      when '--database'
    end
  end
#
#
#
# process options
#
#
#

  count = 0 (not sure I need that?)

     File.open('reference.txt').each do |line|
# puts line
     Regexp.new

  count += 1 if line =~ /^Tag:\s/
  (not sure if I need to escape the ':' ie '\:')

     end
