/**

* @param include If `include` is omitted or has zero length, filter will return `true` by default.
* @param exclude ID must not match any of the `exclude` patterns.
* @param options Additional options.
* @param options.resolve Optionally resolves the patterns against a directory other than `process.cwd()`.
* If a `string` is specified, then the value will be used as the base directory.
* Relative paths will be resolved against `process.cwd()` first.
* If `false`, then the patterns will not be resolved against any directory.
* This can be useful if you want to create a filter for virtual module names.
