      Support files for bash, tcsh and emacs are located in:
        #{prefix}/contrib

      The file for bash is also symlinked to:
        #{etc}/bash_completion.d/cdargs-bash.sh

      Source it from your .bash_profile or .bashrc to get nice aliases and bash completion.

      For zsh use the bash script.

      Consult the cdargs man page for more details and instructions.
