    .Synopsis
    Build script for Packer.

    .Description
    Build script for Packer for all supported platforms and architectures.
    By default the following OSs and architectures are targeted.

    OS:
     * linux
     * darwin
     * windows
     * freebsd
     * openbsd

    Architecture:
     * 386
     * amd64
     * arm

    If the environment variable PACKER_DEV is defined, then the OS and
    architecture of the go binary in the path is used.

    The built binary is stamped with the current version number of Packer,
    the latest git commit, and +CHANGES if there are any outstanding
    changes in the current repository, e.g.

      Packer v0.10.1.dev (3c736322ba3a5fcb3a4e92394011a2e56f396da6+CHANGES)

    The build artifacts for the current OS and architecture are copied to
    bin and $GOPATH\bin.
