# This script is used to start a program from a remote terminal but have it run
# on a virtual terminal. openvt has to be run as root, so we use sudo for that.
# Then, we use sudo --user to run the actual program as the current user. We also
# wrap the invocation in a shell so that we can rediect stdout/stderr to the
# current terminal. Finally, we capture the stderr of openvt and parse it to get
# the tty that the program is being run on so that we can kill it later.
