This may in the end be an awful name, as I'm not really setting out to create a full-fledged SDK. What it is, for now, is a place for common components that I'm using in my Go-based Piazza services. Things like structs defining JSON messages for job creation, S3 upload/download helper utilities, etc.
pzsvc-sdk-go
uses Glide to manage its dependencies. Assuming you are on a Mac OS X, Glide can be easily installed via Homebrew (alternative installation instruction can be found on the Glide webpage).
$ brew install glide
We also make use of Go 1.5's vendor/ experiment, so you'll need to make sure you are running Go 1.5+.
Installing pzsvc-sdk-go
is as simple as cloning the repo, installing dependencies, and installing the package.
$ git clone https://github.com/venicegeo/pzsvc-sdk-go
$ cd pzsvc-sdk-go
$ glide install
$ go install
