Best version tracking tools for embedded software?

Hi to you all, I'm working on a software involving an LPC4370 (Cortex M4 + 2*M0) and LPCXpresso IDE. I'd like to know if someone knows a good version tracking tool for the platform.
My key requisites are:

  • free/cheap for smal teams
  • integration with IDE (LPCXpresso is basically eclipse)
  • possibility of store private projects
  • no need to setup a server

I'd like to apologize if some expression may seem inappropriate, I'm an absolute beginner in version tracking so I'd appreciate your corrections.

Best regards,
Andrea
