# Makes a Tails USB stick: downloads the newest Tails (through Tor when Tor runs
# here), checks its signature and that it is the current release, writes it to
# a USB stick you pick and type the name of, and reads it back to check.
# Everything on the stick is erased. A checked copy is kept for the next stick.
# Where Wren Linux is: WREN_DIR if you set it; else the root-owned copy the
# Wren Linux package installs, which no program running as you can change; else
# your own copy, ~/wren
