licenses under which your works are released, especially when reusing software
from different projects released under different licenses.  It avoids reliance
on fuzzy heuristicts and allows both legal experts and computers to understand
how your project is licensed.  This allows generating a \"bill of materials\"
for software.

This tool downloads full license texts, adds copyright and license information
to file headers, and contains a linter to identify problems.  There are other
tools that have a lot more features and functionality surrounding the analysis
and inspection of copyright and licenses in software projects.  This one is
designed to be simple.")
