-* Most commands accept a `--ignoreVendor` flag, which will then run as if the none of the `_vendor` folders in the module tree existed.
+* Most commands accept a `--ignoreVendorPaths` flag, which will then not use the vendored modules in `_vendor` for the module paths matching the [Glob](https://github.com/gobwas/glob) pattern given.
