# needed for to clean the env if using bundler (like in dev).
#
# this is because the ansible gem module doesn't work right with the bundler
# env vars set, so we need to remove them, but when running in dev we want
# modules written in ruby like nrser.state_mate's `state` script to have
# access to them so it can fire up bundler and get the right libraries.
#
# to accomplish this, we detect Bundler, and when it's present we copy the
# bundler-related env vars (which i found by looking at
# https://github.com/bundler/bundler/blob/master/lib/bundler.rb#L257)
# into a hash to pass around the env sanitization, then copy them into
# corresponding 'QB_DEV_ENV_<NAME>' vars that modules can restore.
#
# we also set a 'QB_DEV_ENV=true' env var for modules to easily detect that
# we're running in dev and restore the variables.
