  The 'your-system-sanity' package detects other packages on your system,
  which are known to facilitate installing other non-free packages,
  or to otherwise disregard the authority of the system package manager,
  and protects you from (accidentally) installing those in the future.

  Also, as any other such packages are identified in the future,
  an updated 'your-system-sanity' package will prompt you for their removal.

  Your feedback/participation is important. It is _your_ system, after all.
  If you notice any problems caused by this package, or notice some package
  which does or does not deserve to be guarded, please do start a discussion.
