puppet-module-puppetlabs-concat binary package in Ubuntu Bionic amd64

 Puppet lets you centrally manage every important aspect of your system
 using a cross-platform specification language that manages all the
 separate elements normally aggregated in different files, like users,
 cron jobs, and hosts, along with obviously discrete elements like
 packages, services, and files.
 .
 This package contains a Puppet module that can construct files from
 fragments.
