Functional constraints¶

• Must run on Windows, Linux and Mac OS X
• Came with an installer.
  • deb / rpm under Linux
  • setup.exe under Windows (made with NSIS for example)
  • .dmg under Mac OS X
• A very simple and friendly usage.
• The user can play a game during downloading. Maybe he have to switch in a particular mode (low network rate).

• All technologies, libraries, resources and tool must be free and open (GPL, CC, BSD, ..).
