Building a debian package for td-agent

If you use td-agent you can build a debian package instead of installing via td-agent-gem. This requires that td-agent is already installed and that you've installed fpm. Then run make in your git directory.

gem install --no-document fpm
git clone https://github.com/logdna/fluent-plugin-logdna
cd fluent-plugin-logdna
gem build fluent-plugin-logdna.gemspec
fpm --input-type gem \
    --output-type deb \
    --no-auto-depends \
    --no-gem-fix-name \
    --depends 'td-agent > 2' \
    --deb-build-depends 'td-agent > 2' \
    fluent-plugin-logdna-*.gem
sudo dpkg -i fluent-plugin-logdna*.deb

Additional Options
