# not a psueber-pretty uninstall script for the Tor bundle package
# . this currently leaves ~/.tor, /var/log/tor and empty
# directories /Library/Tor, /Library/Privoxy (see comment below)
# . this relies on the fact that the startup items directories (if any)
# will be named the same as the package name (ie. Tor)
#
#
# version history
# initial version - 21 may, 2005 - loki der quaeler

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