Collaborative software development platforms such as GitHub simplify the
process of contributing into open source projects by the use of a pull request.
The decision of accepting or rejecting a pull request has to be made by an
integrator. Because reviewing a pull request can be time consuming, social
factors are known to have an important effect on the acceptation of a pull
request. This effect can be especially important for large and complicated pull
request. In this paper we present Git Thermite, a tool to assess the internal
structure of a pull request and simplifying the job of the integrator. Git
Thermite details the structural changes made on the source code. In Git
Thermite we use a pull request business card visual metaphor for describing a
pull request. In this business card, we present the pull request metadata and
describe the modi ed les, and the structural changes in the modi ed source code.
