- git-extras has some nice features... "git summary" and "git effort". These commands show: most active users, most active files (by active days), etc.

- gource can be used to visualize the activity in a repository.

- sloccount and cloc can be used to count lines of code.

- For C/C++/C#, you can run Doxygen, and ask it to generate documentation for undocumented entities. This can make give you another perspective on the code base.

- In runtime there are various tools you can use to audit what a program does... On Linux you've got strace, lsof, wireshark and many others... On Windows you've got Process Monitor from Sysinternals, as well as wireshark.
