description      MIRIAD, an analysis package for radio astronomical data
long_description MIRIAD, the Multichannel Imaging, Reconstruction, Analysis, \
                 and Display package, is a suite of tools for analyzing radio \
                 astronomical observations, from raw data to imaging.

# The license to MIRIAD is somewhat indeterminate, since it has had
# many contributors working at many academic institutions with various
# copyright assignment and licensing policies. It's pretty important
# to straighten this out at some point.

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.
