# 20241021 bkw: Modified by SlackBuilds.org, BUILD=2:
# - support new lua 5.4 and lua51.
# - ARCH=noarch.
# - handle alternate tarball filename, if content-disposition not used.
#   this isn't a github URL, don't see a way to 'canonize' the link.
# - symlinked man pages to match the extra commands (fennel5.1, fenneljit).
# - grammar/punctuation fixes in README.
