Overview

Package coreapi provides direct access to the core commands in IPFS. If you are embedding IPFS directly in your Go program, this package is the public interface you should use to read and write files or otherwise control IPFS.

If you are running IPFS as a separate process, you should use `go-ipfs-api` to work with it via HTTP. As we finalize the interfaces here, `go-ipfs-api` will transparently adopt them so you can use the same code with either package.

**NOTE: this package is experimental.** `go-ipfs` has mainly been developed as a standalone application and library-style use of this package is still new. Interfaces here aren't yet completely stable.
