What's a good way to contribute my RHEL6/7 spec file

[tatsushid]

Hello,

I wrote a RPM spec for RHEL 6/7 with SysVinit script (for RHEL6) and logrotate definition. Now it's published at https://github.com/tatsushid/h2o-rpm

I'd like to contribute it to this project but that spec file is quite different from this one so I appreciate your advise about it. Personally, there are some options:

1. Merge it into one spec file but may have to be added many %if statements
2. Add directories for each distributions and keep their own spec files.
3. Keep these projects as is. Each ones manage their own project.
