  18 # This weird syntax is necessary because some zip archives do not contain a separate
  19 # entry for the root directory but merely a collection of its subdirectories (for instance
  20 # platform-tools). The very first entry in the archive is retrieved, then its path is read and
  21 # finally the part up to the first '/' of the path is retrieved as the root directory of
  22 # the archive. With platform-tools the last part is necessary because otherwise the root directory
  23 # would end up being reported as `platform-tools/adb` as this is the first entry in the archive and
  24 # there's no `platform-tools/` entry

  27 # We need a temporary directory because some archives (emulator) have their root directory named the
  28 # same as a file/directory inside it (emulator has emulator/emulator executable for instance) and
  29 # moving such a file/directory to .. wouldn't work
