Now With Career mode support!
Open folder "Career mode" if you want career mode support, you'll have to go to R&D to unlock modules.
Open folder "It's Free!" if you want not to go to the R&D to unlock modules, they'll be enabled from the start.
As always, Paste 'GameData' in ksp main folder.
This version uses ModuleManager (included 2.7.1) to provide functionality. Unlike my previous release, it does not change your files, it justs appends the MechJeb core at the time of execution.
This does not add MechJeb functionality, it just adds the MechJeb module to the command modules. That means that you don't have to manually add MechJeb while building your ship, it will come embedded on the command module (not physically, but in the code).
I take no responsability for what you do to your game.
I have no relation to the guys behind MechJeb nor Module Manager, I would like to say thanks to them, and guys, keep up the good job!
