The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software -- software which respects your freedom. Unix-like operating systems are built from a collection of applications, libraries, and developer tools -- plus a program to allocate resources and talk to the hardware, known as a kernel. The Hurd, GNU's kernel, is actively developed, but is still some way from being ready for daily use, so GNU is often used with a kernel called Linux. The combination of GNU and Linux is the GNU/Linux operating system, now used by millions and sometimes incorrectly called simply 'Linux'. Being a very large and complex project, and following the Unix philosophy, GNU is subdivided into packages, that is, independent programs with a specific goal. As a mentoring organization in Summer of Code 2011, GNU aims to act as an umbrella for its packages.

Our code repository can be found here: http://code.google.com/p/google-summer-of-code-2011-gnu/, but it is probably better to check the individual GNU projects' source repositories and mailing lists.
