  16 /* The purpose of this file is to let the user choose which packages
  17    to install, and which versions of the package when more than one
  18    version is provided.  The "trust" level serves as an indication as
  19    to which version should be the default choice.  At the moment, all
  20    we do is compare with previously installed packages to skip any
  21    that are already installed (by setting the action to ACTION_SAME).
  22    While the "trust" stuff is supported, it's not really implemented
  23    yet.  We always prefer the "current" option.  In the future, this
  24    file might have a user dialog added to let the user choose to not
  25    install packages, or to install packages that aren't installed by
  26    default. */
