# 1. potentially stop running network
# 2. bootstrap a network from scratch as quickly as possible
# 3. tail -F all the tor log files
#
# NOTE: leaves debris around by renaming directory net/nodes
#       and creating a new net/nodes
#
# Usage:
#    tools/bootstrap-network.sh [network-flavour]
#    network-flavour: one of the files in the networks directory,
#                     (default: 'basic')
