Here's a quick overview, hower:
require 'bzip2'
# Quick shortcuts
data = Bzip2.compress 'string'
Bzip2.uncompress data
# Creating a bz2 compressed file
writer = Bzip2::Writer.new File.open('file')
writer << 'data1'
writer.puts 'data2'
writer.print 'data3'
writer.printf '%s', 'data4'
writer.close
Bzip2::Writer.open('file'){ |f| f << data }
# Reading a bz2 compressed file
reader = Bzip2::Reader.new File.open('file')
reader.gets # => "data1data2\n"
reader.read # => 'data3data4'
reader.readline # => raises Bzip2::EOZError
Bzip2::Reader.open('file'){ |f| puts f.read }Copying
