License Notice Generation as a Library #272
Description
Is your feature request related to a problem? Please describe.
Our crate, notalawyer-build, uses cargo-about to generate license notices at build time.
However, because it uses cargo-about as an executable, we face challenges with version management and build reliability. Since we can't manage this dependency through Cargo.toml, relying on an external binary can sometimes cause build failures when the required configuration files are missing.
Describe the solution you'd like
We propose refactoring the core license notice generation logic into the lib part of cargo-about. This change would allow projects like notalawyer-build to integrate the functionality directly, manage the dependency through Cargo.toml, and avoid issues related to invoking an external binary during the build process.
Describe alternatives you've considered
While continuing to use the binary as-is is an option, it has proven problematic in certain build environments.
