Is that a reference to EEE? I feel like it is, but the capitalisation is confusing me, and now I'm wondering if I'm missing the actual intended meaning.
I think it is. The capitalization is like that because the project name is xCurl, with x. Maybe they should have called it eCurl?
Microsoft's console gaming stuff is very "X"-centric (Xbox, XDK, FATX and so on).
DirectX, ActiveX, etc
I believe that they're relating the X in XCurl to eXtend.
i'm thinking two themes here: the X in xcurl and the famous MS-ism "embrace, extend, extinguish"
