Make saving file to disk optional

[rightaway]

Would you make saving files to disk optional? I'd like to use just the readstreams returned by busboy for the various files and do something else with them rather than save them to disk.

Uhm.. you can use disk as place to save the tmp files, then using the ReadStream for your tasks.
I don't think any problems here.
If you not specify the dest path, it will save the tmp files on tmp folder.

If there's no need to have the file on disk, I don't think it makes sense to consume resources to hit the hard drive in the first place. Many people these days don't store the files locally but stream elsewhere like S3 or a central file server.
