Packaging guidelines for F21

Hi, I am working on draft of Ruby packaging guidelines for F21 [1]. The main two changes are: 1) Simplified packaging of binary extensions (although there is still one caveat [2]). 2) Changes due to automatic dependency generators. If you have any comments, suggestions, please let me know. Vít [1] https://fedoraproject.org/w/index.php?title=PackagingDrafts%2FRuby&di...
