This worked perfect OOTB.
Thanks for this.
Just ran this this rails generator and created the basic structure for a new plugin, uploaded to git, added it to yml, rebuild the app, and it installed flawlessly OOTB.
Visited the plugin tab, and there she way, fully equipped with an OOTB enable /disable setting. 
Thank you very much @j.jaffeux for this easy to use, useful generator.
The only change I made was to do a rm -rf on the included .git directory and re-init git so I could push it to my account; but that was more-than-likely because I’m not very skilled at git and often have to hit git things with a hammer to get them to work as I think they should…
Flawless generator. Thanks again @j.jaffeux
