  - Download the .zip archive with submodules included, extract to destination directory,
    then do 'git reset --hard' and 'git submodule foreach git reset --hard' to correct for
    possibly different newlines. This is done for release versions.
  - Do a git clone of the Github repository into the destination directory.
    This is done for the master branch.
  - Download the .zip archive of a "close enough" release version, extract into a temporary
    directory. Then do a git clone of the Github repository, using the temporary directory
    as a '--reference'. This is done for other versions (such as release branches).
