Subject: Suggestions for improving code

I am trying to convert a plain text file into a tex file with 
somemarkup. I have the following piece of code that does most of the 
work. It works fine but does not "look good". Can someone suggest how 
can I improve this code.

---------------[snip]----------------------
file = File.new(filename, 'r')
texfile = File.open(basename + ".tex", 'w')

CHAPTER = Regexp.new("CHAPTER")
SPACES  = Regexp.new("\s\s\s\s")
BLANK   = Regexp.new(/^\s*$/)

chapter = true
verse   = false
prev_line = ""

file.each_line do |line|
   if chapter && !BLANK.match(line)
     chapter = false
     texfile.puts "\\chapter{#{line.chomp}}"
   elsif CHAPTER.match(line)
     chapter = true
   elsif verse && !SPACES.match(line)
     texfile.puts '\stoplines\stopnarrower'
     texfile.puts line.chomp
     verse = false
   elsif !verse && BLANK.match(prev_line) && SPACES.match(line)
     texfile.puts '\startnarrower\startlines'
     texfile.puts line.chomp
     verse = true
   else
     texfile.puts line.chomp
   end
   prev_line = line
end

Thanks,
