# The script does automatic checking on a Go package and its sub-packages,
# including:
# 1. gofmt         (http://golang.org/cmd/gofmt/)
# 2. gosimple      (https://github.com/dominikh/go-simple)
# 3. unconvert     (https://github.com/mdempsky/unconvert)
# 4. ineffassign   (https://github.com/gordonklaus/ineffassign)
# 5. misspell      (https://github.com/client9/misspell)
# 6. race detector (http://blog.golang.org/race-detector)

# golangci-lint (github.com/golangci/golangci-lint) is used to run each each
# static checker.

# To run on docker on windows, symlink /mnt/c to /c and then execute the script
# from the repo path under /c.  See:
