* Installation

  - In your .emacs:

    (load-file "<path-to-geiser>/elisp/geiser.el")
    (geiser-setup)

  - Check the geiser customization group for some options with:

      M-x customize-group RET geiser RET

    In particular, customize `geiser-repl-guile-binary' (in
    geiser-repl), which should point to a guile-vm executable.

  - To start a REPL, M-x geiser.
