There is More Than RTL

This list does not include units outside of the core RTL. which include FireDAC, DataSnap, EMS, WebBroker, Indy, and DunitX.

The new version of Delphi is bringing to the Linux platform a lot of technology. True, there is no ready-to-use GUI support, but there is lot of keep developers happy.
