Glacier Download Archive

Demonstrates how to download an Amazon Glacier archive. Downloading a Glacier archive is a two step process. First an archive retrieval job is initiated. After it completes, the job output is downloaded (i.e. the archive contents are downloaded.)

Note: This example requires Chilkat v9.5.0.78 or greater.
