# This script used to call (the now deprecated) tsocks as a fallback in case
# torsocks wasn't installed.
# Now, it's just a backwards compatible shim around torsocks with reasonable
# behavior if -v/--verbose or -h/--help arguments are passed.

# May be distributed under the same terms as Tor itself
