# Rodbot foundation
#
# Once the Rodbot gem has been required, use +boot+ to spin up the foundation:
#
#   Rodbot.boot                          # current directory is root directory
#   Rodbot.boot(root: '/path/to/root')   # explicit root directory
#
# This gives you access to the following shortcuts (in order of loading):
#
# * +Rodbot.env+ -> {Rodbot::Env}
# * +Rodbot.credentials+ -> {Dry::Credentials}
# * +Rodbot.config+ -> {Rodbot::Config#config}
# * +Rodbot.plugins+ -> {Rodbot::Plugins}
# * +Rodbot.db+ -> {Rodbot::Db#db}
# * +Rodbot.log+ -> {Rodbot::Log#log}
# * +Rodbot.request+ -> {Rodbot::Rack#request}
# * +Rodbot.say+ -> {Rodbot::Relay#say}
