Subject: code analysis request

I wrote the below code in maybe 10 minutes.  It seems to do the job,
but I'm sure it could be better.  Any ideas?

# Examines a subversion directory.
# If a file has been added, add the file to the repository.
# If a file has been deleted, delete the file from the repository.
# And save all modified files.
# And then do a 'svn up'.

# Meant to do automated versioned backups of a directory for
# non-technically inclined users.


# Utility functions
class String
  def get_filename
    self.split[1]
  end
end

def get_status line
  line.split[0]
end

def new_file? line
  get_status(line) == "?"
end

def removed_file? line
  get_status(line) == "!"
end

def add_file file_name
  puts "adding file: <#{file_name}>"
  system "svn add '#{file_name}'"
end

def remove_file file_name
  puts "removing file: <#{file_name}>"
  system "svn del '#{file_name}'"
end

def hidden_filename line
  line.get_filename[0,1] == "." if line.size > 0
end

# Get svn stuff and process it.
svn_output = `svn status`
svn_output.split("\n").each do |line|
  # a line should look something like "M         some/dir/file_name"
  unless hidden_filename(line)
    add_file line.get_filename if new_file? line
    remove_file line.get_filename if removed_file? line
  end
end
system "svn commit -m 'autocommited!'"
system "svn up"
