|  |  * **Usage:** | ||
|  |  * ```sh
 | ||
|  |  * node mock-ngcc-version-marker <entry-point> <mock-ngcc-version> | ||
|  |  * | ||
|  |  * # Example: | ||
|  |  * # node mock-ngcc-version-marker @angular/material/button 3.0.0 | ||
|  |  * ```
 | ||
|  |  * | ||
|  |  * Ngcc marks entry-points as processed by adding marker properties in their `package.json`. It uses | ||
|  |  * a version as a marker in order to be able to distinguish entry-points processed by a different | ||
|  |  * ngcc version (e.g. an older version after an update) and perform the necessary clean-up. | ||
|  |  * | ||
|  |  * This script replaces the ngcc version marker in an entry-point's `package.json` to make it appear | ||
|  |  * as if it were processed by a different version of ngcc. This allows testing the clean-up logic | ||
|  |  * without the overhead of actually installing a different ngcc version, compiling the dependencies, | ||
|  |  * then installing the current version and compiling again. | ||
