+/**
+ * <h3>TO OTHER MOD AUTHORS THAT WANT TO BUNDLE KOTLIN AND ARE RUNNING INTO CONFLICTS WITH NEU:</h3>
+ *
+ * <p>
+ * NEU allows you to stop it from loading Kotlin by specifying one of two properties in the
+ * {@link Launch#blackboard}. This needs to be done before {@link #injectIntoClassLoader}, so do it in your Tweakers
+ * constructor. Most likely you will not need to do this, since different Kotlin versions rarely contain breaking changes
+ * and most people do not use any of the newer features.
+ * </p>
+ *
+ * <ul>
+ * <li>
+ * {@code neu.relinquishkotlin.ifbelow}. Set to an int array, like so: {@code [1, 7, 20]}.
+ * See {@link #BUNDLED_KOTLIN_VERSION}
+ * </li>
+ * <li>
+ * {@code neu.relinquishkotlin.always}. If set to {@code true}, will prevent NEU from loading any kotlin.
+ * Before you use this, consider: are you sure you are always gonna have a more update version of Kotlin than NEU?
+ * And, even if you are sure, do you really want to block us from updating our Kotlin, after we so graciously allowed
+ * you to stop us from breaking your mod.
+ * </li>
+ * <li>
+ * Additionally, setting the jvm property {@code neu.relinquishkotlin} to 1, will prevent NEU from loading Kotlin.
+ * </li>
+ * </ul>
+ *
+ * <p>
+ * Sadly the Kotlin stdlib cannot be relocated (and we wouldn't want to do that either, because it would prevent us
+ * from interoperating with other Kotlin mods in some ways (for example: reflection)), so in order to minimize conflicts,
+ * we allow other mods to stop us from loading Kotlin. Usually this would be handled with a common library provider, but
+ * since those come bundled with literal Remote Code Execution, Cosmetics, and unskippable Updates that can just not be
+ * considered a good thing by any developer with a conscience nowadays, those are not an option for us. Another option
+ * would be a dependency resolution algorithm like Jar-in-Jar, but sadly we have to mod on a 7 year old modding platform,
+ * so we have to make due with our crude hack.
+ * </p>
