Something like this?

packing:
$ ruby pack.rb file1 file2 > my_package.rb

extracting:
$ ruby my_package.rb

the code:

#--- pack.rb ---
EXTRACT = <<EOF
numfiles = DATA.gets.to_i
files = []
numfiles.times do
   files << [DATA.gets.chomp, DATA.gets.to_i]
end
numfiles.times do |i|
   file, size = files[i]
   File.open(file, "w") { |f| f.write(DATA.read(size)) }
end
__END__
EOF

puts EXTRACT
puts ARGV.size
ARGV.each do |f|
   puts f
   puts File.size(f)
end
ARGV.each do |f|
   STDOUT.write(IO.read(f))
end
# --- end pack.rb ---
