About the testing transition known as auto-libunwind

[T o n g <mlist4suntong@yahoo.com>]

Hi, 

I want to adopt the par2cmdline package, but on its QA page, 
http://packages.qa.debian.org/p/par2cmdline.html
it says, 

,-----
| "This package is part of the ongoing testing transition known as
| auto-libunwind. Please avoid uploads unrelated to this
| transition, they would likely delay it and require supplementary
| work from the release managers."
`-----

what's the impact on me adopting/building/uploading the package?

Thanks
