CMake Release Script Usage:
  $0 [command]

Typical usage:
  Cleanup remote host release directory:

    $0 remote <host> clean

  Create binary release tarball:

    $0 remote_binary <host>

  Create source release tarball:

    $0 remote_source <host>

  Upload tarballs:

    $0 upload

  Create and upload cygwin package:

    $0 cygwin_package
    $0 cygwin_upload

Available commands:
