About
By the time of this writting there are three pages of Gravatar clients written in PHP and listed on Packagist. 60% of them are framework agnostic, the rest are created for a specific framework (Laravel, Nette, Kohana, Silex to name a few). Some of the packages are not maintained anymore (3 years old package), some of them does not have a repository behind (they are deleted from Github). By further inspection it turns out that some of them does not even have a README or documentation. So out of 45 packages (there are 15 packages on one page) 5 or six deserves to be mentioned at all. That's a shame. (See: Phil Sturgeon's PHP Wars post.) This initiative tries to collect the best ideas from all existing implementations to provide an easy to use, but a powerfull tool to integrate Gravatar into applications. Some new, never seen tools will also be introduced.
To package authors! You are more than welcome to contribute your projects to this initiative. This is not trying to be the de facto implementation, also the fact that I didn't find any decent one doesn't mean there aren't any.
