# The formula uses archive.org for the homepage and a mirrored version of the
# last available archive. There seems to be some newer development in the
# ELF Tool Chain project (https://sourceforge.net/p/elftoolchain/wiki/Home/)
# but they don't create separate libelf releases. Altogether, there's nothing
# we can currently check for a new version, so we're skipping this until
# something changes.
