  7. # will be named the same as the package name (ie. Tor)

  14. # comments
  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
