This module lacks complete documentation due to me not currently able to write it. Please, see some notes for
L<C<WWW::GCloud>|https://raku.land/zef:vrurg/WWW::GCloud> framework. And look into I<exmaples/> where I tried to provide
meaningful code to follow.


This module is pre-beta, pre-anything. It is incomplete and likely not well thought out at places. But it already
lets you do a lot with your storages.


If there is anything you need but it is missing then, please, consider implementing it and submitting a PR. Any other
approach would barely proces any outcome for what I do apologize!


Either way, this module can be used as a reference implementation for a C<WWW::GGCloud> API.
