Several tools are general purpose and can be used to inspect and manipulate the storage files that software using the NSS library creates and modifies. Other tools are only used for testing purposes. -- `test` and `gtests` contain the NSS test suite. While `test` contains shell scripts to drive test programs in `cmd`, `gtests` holds a set of [gtests](https://github.com/google/googletest). -A more comprehensible overview of the NSS folder structure and API guidelines can be found [here](https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/NSS_API_Guidelines). +- `cmd` contains a set of various tool programs that are built with NSS.
