wrappederr is a simple program to integrate with go vet checks

It statically analyses all functions which include error in their return type and check whether these errors are wrapped using the errors.Wrap function.

To use it, install the program and run go vet like so:

go vet --vettool=$(which wrappederr) ./...

NOTE: This is a POC where there is a possibility that the error is indeed returned wrapped from another function but it unwrapped in the current function, causing it to display false positives.
