/**
- * A startup class that checks that a suitable JRE environment is being run.
- * If the environment is too old the execution is canceled, and if OpenJDK is being
- * used warns the user of problems and confirms whether to continue.
+ * The first class in the OpenRocket startup sequence. This class is responsible
+ * for setting up the Application class with the statically used subsystems
+ * (logging and translation) and then delegating to Startup2 class.
+ * <p>
+ * This class must be very cautious about what classes it calls. This is because
+ * the loggers/translators for classes are initialized as static final members during
+ * class initialization. For example, this class MUST NOT use the Prefs class, because
+ * using it will cause LineStyle to be initialized, which then receives an invalid
+ * (not-yet-initialized) translator.
