- * Command-line tool that produces a widened copy of a JAR for use as a

- *
- * Usage:
- *   java -jar jar-widener.jar <input.jar> <output.jar> [file.accesswidener ...]
- *
- * The output JAR is identical to the input JAR except that every class
- * targeted by the access widener entries has its access flags patched:
- *   accessible  → public
- *   extendable  → public + non-final
- *   mutable     → non-final field
- *
- * Intended for use as a Gradle task so IntelliJ sees the already-widened
- * class when you Ctrl+click NMS code, and javac compiles without complaints.
