How can I merge two Delphi projects?

Is there a way to merge two Delphi projects into one?

In one proje开发者_如何学运维ct I have 3 different forms with different stuff on them, but I would like to add a program I have coded a while ago into a new form in my program.

In the Project Manager, right-click your application, and select "Add". Select then the unit (*.pas) file of the form (e.g. Unit1.pas). The corresponding form (e.g. Form1.dfm) will be added with the unit.
