-# multipartstreamer
-
-Package multipartstreamer helps you encode large files in MIME multipart format
-without reading the entire content into memory.  It uses io.MultiReader to
-combine an inner multipart.Reader with a file handle.
-
-```go
-package main
-
-import (
-  "github.com/technoweenie/multipartstreamer.go"
-  "net/http"
-)
-
-func main() {
-  ms := multipartstreamer.New()
-
-  ms.WriteFields(map[string]string{
-    "key":			"some-key",
-    "AWSAccessKeyId":	"ABCDEF",
-    "acl":			"some-acl",
-  })
-
-  // Add any io.Reader to the multipart.Reader.
-  ms.WriteReader("file", "filename", some_ioReader, size)
-
-  // Shortcut for adding local file.
-  ms.WriteFile("file", "path/to/file")
-
-  req, _ := http.NewRequest("POST", "someurl", nil)
-  ms.SetupRequest(req)
-
-  res, _ := http.DefaultClient.Do(req)
-}
-```
-
-One limitation: You can only write a single file.
-
-## TODO
-
-* Multiple files?
