   3 # not a psueber-pretty uninstall script for the Tor bundle package
   4 #       . this currently leaves ~/.tor, /var/log/tor and empty
   5 #               directories /Library/Tor, /Library/Privoxy (see comment below)
   6 #       . this relies on the fact that the startup items directories (if any)
   7 #               will be named the same as the package name (ie. Tor)

  15 # loki: because of the way the Tor package installs itself (the root directory
  16 #       is the filesystem root, as opposed to the much nicer way that privoxy
  17 #       installs itself with the privoxy home (/Library/Privoxy) as its
  18 #       install root directory), i thought it more prudent to leave empty
  19 #       directories laying around rather than try to incorrectly intuit from
  20 #       the bom contents what directories should exist and which ones could be
  21 #       deleted (ie, the Tor package has /Library listed in its bom --
  22 #       obviously this is a Bad Thing(tm) to delete).
  23 #       + when the Tor installer is changed, this uninstaller could be modified.
  24 # loki: /bin/ps, when run from a terminal window in osX, restricts information
  25 #       based on the width of the window. an 80 col window will stupidly cause
  26 #       the grep search for the privoxy pid to not find the pid, whereas the grep
  27 #       in a wider window succeeds. consider using killall. in the meantime,
  28 #       advise uninstall runners to drag wide their terminal window.. ugh
