Options

Most options are passed through from npm-license-crawler.

param	default	description
--start directory-path	["./"]	path to the directory the license search should start from. If omitted the current working directory is assumed. Can be declared multiple for multiple entry points.
--exclude directory-path	[]	path to a directory to be excluded (and its subdirectories) from the search (behaves like --start)
--unknown	false	show only licenses that can't be determined or have been guessed.

--production	false	show only production dependencies
--development	false	show only development dependencies
--onlyDirectDependencies	false	show only direct dependencies licenses, i.e., don't list dependencies of dependencies.
--omitVersion	false	omit version numbers in result (e.g. "npm-license-crawler@0.1.5" becomes "npm-license-crawler")
--relativeLicensePath	false	output the relative file path for license files.
--allow	[]	list of packages that doen't throw an error regardless of there license. Like with the --start argument, you can specify it mutliple times

How does it work?

Licenses can be categorized with a hierarchie. This package checks which license you are using and in which category it belongs. Then it crawls all your licenses dependencies and checks if there licenses are in the same category as yours or below. If not, it throws an error.

License compatiblity

(currently, the implementation is a bit simpler, as explained above)
