This repository is a shared repository for header files, protobuf definitions, and scripts. It is linked into other repositories in the Hydro project using git submodules. This README provides a brief overview of the contents of this repository. This repository will not change frequently and should only contain code that is used across multiple Hydro subprojects.

• cmake: This directory has three helpers that are useful for any CMake-based project: CodeCoverage.cmake uses lcov and gcov to automatically generate coverage information; DownloadProject.cmake automatically downloads and configured external C++ dependencies; and clang-format.cmake automatically runs the clang-format tool on all C++ files in a project.
• include: A variety of Hydro C++ header files, including shared lattice definitions, a Anna KVS client, shared typedefs and other utilities.
• proto: Project API-level protobuf definitions.
• scripts: Various helper scripts that install dependencies and simplify creating Travis build processes.
• vendor: CMake configuration for Hydro vendor dependencies (ZeroMQ, SPDLog, and Yaml-CPP).
