Right now the rpm is only available for download but not to be used by package managers like e.g. yum.

To enhance the availability of henplus for rpm-based distributions there could be set up a repo together with an .repo file that can be put into the yum.repos.d folder.
An even better alternative would be to pull it into the fedora distro, so that users have henplus available without doing anything.

For other rpm-based distros the package management must be checked out on what's required for integration.
