# 20200922 bkw: man page originally came from:
# http://deb.debian.org/debian/pool/main/s/shellcheck/shellcheck_0.7.1-1.debian.tar.xz
# We can't use the shellcheck source any more, it no longer ships the
# man page: it now uses pandoc to generate the man page. We don't make
# this build depend on pandoc because it has 138 (!) dependencies.
# Since the man page is pretty small, I just extracted it from the
# Debian package and added it to our git repo.
