It's been a month and a half since I started working on the Mercurial project as part of the Google Summer of Code program. Mercurial is a free, distributed source control tool written in Python that efficiently handles projects of any size and offers an easy and intuitive interface while the Google Summer of Code is a global program that offers student developers stipends to write code for various open source software projects.
