Lazarus + Free Pascal = Delphi

Some time ago I’ve used Windows and developed on Delphi but without some outstanding achievements. Delphi is quite good development environment but it’s commercial and it works only under Windows. Many of you know about Kilyx. It allows to develop on Delphi under Linux. But it’s again commercial software.
Recently, I’ve found quite interesting project – Lazarus. This is a library for Free Pascal that emulate Delphi. So, it might be useful for adherents of Delphi and Pascal.
