# Simple setup script invoker for bash with completion
# Author: Lukas Nellen
#
# Setup scripts are in $HOME/setup.d
# They get sourced to modify the current shell's environment
#
# Special case if $PYENV set to point to a directory with python virtual envs:
#   setup py "the-env"
# will activate the python environment "the-env" in ${PYENV}
#
# Configure automatic name completion
