  Networks of collaboration between engineers are reflected in traces of
developers' activity in version control systems (VCSs). Extracting data from
Git repositories is an essential task for researchers and practitioners working
on socio-technical analysis, but it requires substantial engineering work. With
increasing interest in analysing socio-technical data and applying it in
practice, there are no flexible and easily reusable tools to retrieve
socio-technical information from VCSs. With no common reusable toolkit existing
for this task, the burden of mining diverts the focus of researchers from their
core research questions. In this paper, we present TNM -- an open-source tool
for mining socio-technical data from Git repositories. TNM is fast, flexible,
and easily extensible. TNM is available on GitHub:
