How to unpackage (or unpack, unzip, extract) a chaincode?

Anyone knows how do we unpackage a chaincode? tar -xvf does not work.
$ tar -xvf mycc.1.0
tar: Unrecognized archive format
tar: Error exit delayed from previous errors.
in above mycc.1.0 is what got installed on the peer when we ran peer chaincode install.
$ ls -al mycc.1.0

If you're using the new lifecycle commands, the chaincode package is a gzip compressed tar; if you're using the legacy (lscc) commands, the package is a protobuf encoded chaincode deployment spec. You'll need to unmarshal that message to get to the code package tar file.

Here is a very, very basic program to ingest the chaincode package and output a tarball of it: https://github.com/yeasy/blockchain_guide/blob/master/_code/unpack_chaincode.go
