The syntax of the above declarations is for bourne shell (e.g. sh, bash).

For bourne shell, you can just use `. ./ENVIRONMENT', or merge the
declarations with ~/.profile or ~/.bashrc etc.

For csh, I think that you will need to use setenv.

export makes the variables environment variables rather than shell
variables, so that they are available to processes started from the
shell, e.g. kaffe.

It should include the directory that contains the shared libraries
(the libkaffe*.so files).
