27 This module queries Amazon's Elastic Compute Cloud Metadata service
28 described at:
29 http://docs.amazonwebservices.com/AWSEC2/2007-08-29/DeveloperGuide/AESDG-chapter-instancedata.html
30 . It also fetches 'user_data' which follows the same API but is often
31 no considered part of the metadata service by Amazons documentation.
32 The module also ships with a command line tool ec2meta that provides
33 the same data.
34
35 THIS MODULE WILL ONLY WORK ON AN EC2 INSTANCE.
36
38 new()
39 A constructor - for convenience all methods are class methods.

41 all_data()
42 Returns a hash ref of all the keys, and their values. Note: this means
43 that public_keys is a listing of the keys not a listing of the values.
44
45 available_data()
46 A listing of all the meta_data and user_data available from this
47 module.
