# glvis (like mfem) is downloaded from a URL shortener at request
# of upstream author Tzanio Kolev <tzanio@llnl.gov>. See here:
# https://github.com/mfem/mfem/issues/53
#
# The following procedure should be used to verify security when a
# new version is added:
#
# 1. Verify that no checksums on old versions have changed.
#
# 2. Verify that the shortened URL for the new version is listed at:
# https://glvis.org/download/
#
# 3. Use http://getlinkinfo.com or similar to verify that the
# underling download link for the latest version comes has the
# prefix: http://glvis.github.io/releases
#
# If this quick verification procedure fails, additional discussion
# will be required to verify the new version.
#
# glvis does not need mfem+mpi but will build that by default, to just build
# a serial mfem: `spack install glvis ^mfem~mpi~metis'
