This example shows how one could perform statistics on Git repository.
Install libgit2 development files. For Debian-like Linux - use apt-get install libgit2-dev. For Windows - pacman -S mingw-w64-x86_64-libgit2 in MinGW64 console, if you do not have MSYS2-MinGW64 installed - install it first as described in http://www.msys2.org
To build use ../gradlew assemble.
To run use ../gradlew runReleaseExecutableGitChurn or execute the program directly:
./build/bin/gitChurn/main/release/executable/gitchurn.kexe ../../
It will print most frequently modified (by number of commits) files in repository.
