[Pas2js] Lazarus trunk and FPC source folder issue

[Mgr. Janusz Chmiel]

Please, can I simply point Lazarus to The source folder with FPC compiler
which I have downloaded by using SVN?
Or if I want to successfully setup Lazarus dialog to add FPC source folder,
I must really use The FPC source folder which is The part of some Lazarus
which contain installer?
I Am very nicely and strongly impressed by The Lazarus and Pas2js
integration. It wodk really excellently.
