#
# The following procedure should be used to verify security when a
# new verison 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:
# http://mfem.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://mfem.github.io/releases
#
# If this quick verification procedure fails, additional discussion
# will be required to verify the new version.
