SYNOPSIS:

a good exercise is to read the test.rb to understand how the library works deeper

require "mp3info"
# read and display infos & tags
Mp3Info.open("myfile.mp3") do |mp3info|
  puts mp3info
end

# read/write tag1 and tag2 with Mp3Info#tag attribute
# when reading tag2 have priority over tag1
# when writing, each tag is written.
Mp3Info.open("myfile.mp3") do |mp3|
  puts mp3.tag.title   
  puts mp3.tag.artist   
  puts mp3.tag.album
  puts mp3.tag.tracknum
  mp3.tag.title = "track title"
  mp3.tag.artist = "artist name"
end

Mp3Info.open("myfile.mp3") do |mp3|
  # you can access four letter v2 tags like this
  puts mp3.tag2.TIT2
  mp3.tag2.TIT2 = "new TIT2"
  # or like that
  mp3.tag2["TIT2"]
  # at this time, only COMM tag is processed after reading and before writing
  # according to ID3v2#options hash
  mp3.tag2.options[:lang] = "FRE"
  mp3.tag2.COMM = "my comment in french, correctly handled when reading and writing"
end
