Hi Brad and Lei,

Are there any concerns about having libmimetic for multi-part parsing.
Please have a look at the below mail.

If there are any other suggestions, please post in here.

> -X POST https://$bmc/ibm/v1/files/partitions/"
> The above multipart request contains the file contents separated by a
