You can download prebuilt binaries if you prefer. Check the Release page to download the latest jp executable. There are binaries available for Windows, Linux, Mac, FreeBSD. If you have a go 1.5 environment setup, you can build cross platform binaries by running scripts/build-all-platforms. This will put executables in the build/ directory and each executable will be named jp-<platform>, e.g jp-darwin-amd64, jp-linux-386, etc.
