packer-graphite.json

/*

  This is my source version of the packer-graphite build.  It contains
  comments which are stripped out of the file before it's fed to the
  Packer.io build process.  There should also be an graphite.json file
  in this directory.  That file is the same as this one, sans comments.

  If you want to run the build, but don't have the strip-json-comments
  program installed, you should build it using the graphite.json file.
