// Upload Managers

|
// The s3manager package's Uploader provides concurrent upload of content to S3
|
|
// by taking advantage of S3's Multipart APIs. The Uploader also supports both
|
|
// io.Reader for streaming uploads, and will also take advantage of io.ReadSeeker
|
|
// for optimizations if the Body satisfies that type. Once the Uploader instance
|
|
// is created you can call Upload concurrently from multiple goroutines safely.

|
// sess := session.Must(session.NewSession())
