# Little helpful message. We could consider adding a patch to install

notes "
MIRIAD programs are not in your \$PATH by default. Type 'source\
${prefix}/lib/miriad/automiriad.sh' in your shell to set it up to use\
MIRIAD. If you use csh or tcsh, 'source ${prefix}/lib/miriad/automiriad.csh'\
instead. The 'source' keyword is important! You can put this command in\
your .profile or other shell initialization files to make this setup automatic.
