# The formula uses archive.org for the homepage and a mirrored version of 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.
