[fpc-pascal] Google API, OAuth2 and Windows

[Lubos Pintes]

Hello,
I want to use Google Calendar API with FPC 3.0.0 under Windows. I 
grabbed necessary units from SVN, because it seems to me that they are 
not available under FPC 3.0.0 units.
My question: how can I handle OAuth2? Do I need an external library like 
Synapse under Windows, or can I use existing units from FPC 3.0.0?
I noticed that there are units like fpoauth2, but I have no idea how to 
use them.
Thanks.
