Installation is simple:

  cp -r readline{,.scm} `gauche-config --sitelibdir`

A Makefile is provided even more convenience:

  make install

The following invocation shows how you can play with the examples
without installing:

  gosh -I. examples/repl.scm -e '(main (list))'

gosh 0.6.1's `gosh --help` does not mention the -e flag; the info
documentation does, however.
