 - **CoDep** extracts package and class dependencies of a Python module and serialized them as JSON structures, composed of edges and nodes, thus easing the bridging with front-end technologies for graph visualizations. It combines [PyReverse](https://pypi.org/project/pyreverse/) and [NetworkX](https://networkx.github.io/).
 - **CoQua** retrieves code quality insights, such as checks about line-code’s length, well-formed variable names, unused imported modules and code clones. It uses [PyLint](https://www.pylint.org/) and [Flake8](http://flake8.pycqa.org/en/latest/index.html). The tools can be activated by passing the corresponding category: `code_quality_pylint` or `code_quality_flake8`.
 - **CoVuln** scans the code to identify security vulnerabilities such as potential SQL and Shell injections, hard-coded passwords and weak cryptographic key size. It relies on [Bandit](https://github.com/PyCQA/bandit).
-- **CoLic** scans the code to extract license information. It currently supports [Nomos](https://github.com/fossology/fossology/tree/master/src/nomos) and [ScanCode](https://github.com/nexB/scancode-toolkit). They can be activated by passing the corresponding category: `code_license_nomos`, `code_license_scancode`, or `code_license_scancode_cli`.
+- **CoLic** scans the code to extract license & copyright information. It currently supports [Nomos](https://github.com/fossology/fossology/tree/master/src/nomos) and [ScanCode](https://github.com/nexB/scancode-toolkit). They can be activated by passing the corresponding category: `code_license_nomos`, `code_license_scancode`, or `code_license_scancode_cli`.
 - **CoLang** gathers insights about code language distribution of a git repository. It relies on [Linguist](https://github.com/github/linguist) and [Cloc](http://cloc.sourceforge.net/) tools. They can be activated by passing the corresponding category: `code_language_linguist` or `code_language_cloc`.
