  -### Historial macOS SDK Extraction Notes
  -
  -Our previously used macOS SDK (`MacOSX10.11.sdk`) can be extracted from
  -[Xcode 7.3.1 dmg](https://developer.apple.com/devcenter/download.action?path=/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg).
  -The script [`extract-osx-sdk.sh`](./extract-osx-sdk.sh) automates this. First
  -ensure the DMG file is in the current directory, and then run the script. You
  -may wish to delete the `intermediate 5.hfs` file and `MacOSX10.11.sdk` (the
  -directory) when you've confirmed the extraction succeeded.
  -
  -```bash
  -apt-get install p7zip-full sleuthkit
  -contrib/macdeploy/extract-osx-sdk.sh
  -rm -rf 5.hfs MacOSX10.11.sdk
  -```

  `binutils` (`ld`, `ar`, etc) and DMG authoring tools.
