+# NPM License Checker
+
+[![Build Status](https://www.travis-ci.org/davglass/license-checker.svg?branch=master)](https://www.travis-ci.org/davglass/license-checker)
+
+_Due to legal issues I - for now - had to remove the `--relativeModulePath` option again. I hope I can bring it back soon._
+
+_This is a fork of davglass' `license-checker v.25.0.1` - I simply added a new option `--relativeModulePath` for stripping the local absolute path portions from modules (`--relativeLicensePath` already does this for the license file paths). Since that module doesn't seem to be updated regularly, I created this module for use in our workplace. A pull request has also been created for bringing that new option into the original module (see https://github.com/davglass/license-checker/pull/223). Also, I upgraded several node modules for this fork that are not upgraded in the original module. The latter is not part of my pull request._
+
+_As of v26.0.0 the `exclude` argument has been changed into `excludeLicenses` in order to prevent confusion and better align it with the `excludePackages` argument. Also, the argument `includeLicenses` has been added for listing only packages that include the licenses listed._
+
+_As of v17.0.0 the `failOn` and `onlyAllow` arguments take semicolons as delimeters instead of commas. Some license names contain commas and it messed with the parsing._
+
+Ever needed to see all the license info for a module and its dependencies?
+
+It's this easy:
+
+```shell
+npm install -g license-checker-rseidelsohn
+
+mkdir foo
+cd foo
+npm install yui-lint
+license-checker-rseidelsohn
+```
+
+You should see something like this:
+
+```
+├─ cli@0.4.3
+│  ├─ repository: http://github.com/chriso/cli
+│  └─ licenses: MIT
+├─ glob@3.1.14
+│  ├─ repository: https://github.com/isaacs/node-glob
+│  └─ licenses: UNKNOWN
+├─ graceful-fs@1.1.14
+│  ├─ repository: https://github.com/isaacs/node-graceful-fs
+│  └─ licenses: UNKNOWN
+├─ inherits@1.0.0
+│  ├─ repository: https://github.com/isaacs/inherits

+│  └─ licenses: MIT

+│  └─ licenses: UNKNOWN
+└─ yui-lint@0.1.1
+   ├─ licenses: BSD
+      └─ repository: http://github.com/yui/yui-lint
+```
+
+An asterisk next to a license name means that it was deduced from
+an other file than package.json (README, LICENSE, COPYING, ...)
+You could see something like this:
+
+```
+└─ debug@2.0.0
+   ├─ repository: https://github.com/visionmedia/debug
+   └─ licenses: MIT*
+```
+
+## Options
+
+- `--production` only show production dependencies.
+- `--development` only show development dependencies.
+- `--start [filepath]` path of the initial json to look for
+- `--unknown` report guessed licenses as unknown licenses.
+- `--onlyunknown` only list packages with unknown or guessed licenses.
+- `--markdown` output in markdown format.
+- `--json` output in json format.
+- `--csv` output in csv format.
+- `--csvComponentPrefix` prefix column for component in csv format.
+- `--out [filepath]` write the data to a specific file.
+- `--files [path]` copy all license files to path and rename them to `module-name`@`version`-LICENSE.txt.
+- `--customPath` to add a custom Format file in JSON
+- `--excludeLicenses [list]` exclude modules which licenses are in the comma-separated list from the output
+- `--includeLicenses [list]` include only modules which licenses are in the comma-separated list from the output
+- `--relativeLicensePath` output the location of the license files as relative paths
+- `--summary` output a summary of the license usage',
+- `--failOn [list]` fail (exit with code 1) on the first occurrence of the licenses of the semicolon-separated list
+- `--onlyAllow [list]` fail (exit with code 1) on the first occurrence of the licenses not in the semicolon-seperated list
+- `--includePackages [list]` restrict output to the packages (either "package@fullversion" or "package@majorversion" or only "package") in the semicolon-seperated list
+- `--excludePackages [list]` restrict output to the packages (either "package@fullversion" or "package@majorversion" or only "package") not in the semicolon-seperated list
+- `--excludePrivatePackages` restrict output to not include any package marked as private
+- `--direct` look for direct dependencies only
+
+## Exclusions
+
+A list of licenses is the simplest way to describe what you want to exclude.
+
+You can use valid [SPDX identifiers](https://spdx.org/licenses/).
+You can use valid SPDX expressions like `MIT OR X11`.
+You can use non-valid SPDX identifiers, like `Public Domain`, since `npm` does
+support some license strings that are not SPDX identifiers.
+
+## Examples
+
+```
+license-checker-rseidelsohn --json > /path/to/licenses.json
+license-checker-rseidelsohn --csv --out /path/to/licenses.csv
+license-checker-rseidelsohn --unknown
+license-checker-rseidelsohn --customPath customFormatExample.json
+license-checker-rseidelsohn --excludeModules 'MIT, MIT OR X11, BSD, ISC'
+license-checker-rseidelsohn --includePackages 'react@16.3.0;react-dom@16.3.0;lodash@4.3.1'
+license-checker-rseidelsohn --excludePackages 'internal-1;internal-2'
+license-checker-rseidelsohn --onlyunknown
+```
+
+## Custom format
+
+The `--customPath` option can be used with CSV to specify the columns. Note that
+the first column, `module_name`, will always be used.
+
+When used with JSON format, it will add the specified items to the usual ones.
+
+The available items are the following:
+
+- name
+- version
+- description
+- repository
+- publisher
+- email
+- url
+- licenses
+- licenseFile
+- licenseText
+- licenseModified
+
+You can also give default values for each item.
+See an example in [customFormatExample.json](customFormatExample.json).
+
+## Requiring
+
+```js
+var checker = require('license-checker');
+
+checker.init(
+  {
+    start: '/path/to/start/looking',
+  },
+  function(err, packages) {
+    if (err) {
+      //Handle error
+    } else {
+      //The sorted package data
+      //as an Object
+    }
+  }
+);
+```
+
+## Debugging
+
+license-checker uses [debug](https://www.npmjs.com/package/debug) for internal logging. There’s two internal markers:
+
+- `license-checker-rseidelsohn:error` for errors
+- `license-checker-rseidelsohn:log` for non-errors
+
+Set the `DEBUG` environment variable to one of these to see debug output:
+
+```shell
+$ export DEBUG=license-checker-rseidelsohn*; license-checker-rseidelsohn
+scanning ./yui-lint
+├─ cli@0.4.3
+│  ├─ repository: http://github.com/chriso/cli
+│  └─ licenses: MIT
+# ...
+```
+
+## How Licenses are Found
+
+We walk through the `node_modules` directory with the [`read-installed`](https://www.npmjs.org/package/read-installed) module. Once we gathered a list of modules we walk through them and look at all of their `package.json`'s, We try to identify the license with the [`spdx`](https://www.npmjs.com/package/spdx) module to see if it has a valid SPDX license attached. If that fails, we then look into the module for the following files: `LICENSE`, `LICENCE`, `COPYING`, & `README`.
+
+If one of the those files are found (in that order) we will attempt to parse the license data from it with a list of known license texts. This will be shown with the `*` next to the name of the license to show that we "guessed" at it.
