# Path Plugin
# -----------
# Adds each line from $HOME/.path to your PATH variable.
# Environment variables will be evaluated in this file for you, so you
# can use references like $HOME/bin.
#
# Use `reload_path` to update $PATH if you change $HOME/.path

    if [ $CUSTOM_PATH ]; then
        # Determine what the original path was before we modified it be removing
        # our CUSTOM_PATH.  This way we don't double-up entries on the path when
        # manually calling reload_path.
