+;;; Java bootstrap toolchain.
+;;;
+
+;; The Java bootstrap begins with Jikes, a Java compiler written in C++. We
+;; use it to build the SableVM standard library and virtual machine, which are
+;; written in a simpler dialect of Java and C, respectively. This is
+;; sufficient to build an older version of Ant, which is needed to build an
+;; older version of ECJ, an incremental Java compiler, both of which are
+;; written in Java.
+;;
+;; ECJ is needed to build the latest release of GNU Classpath (0.99).
+;; Classpath (> 0.98) is a requirement for JamVM, a more modern implementation
+;; of the Java virtual machine.
+;;
+;; With JamVM we can build the latest development version of GNU Classpath,
+;; which has much more support for Java 1.6 than the latest release. Since
+;; the previous build of JamVM is limited by the use of GNU Classpath 0.99 we
+;; rebuild it with the latest development version of GNU Classpath.
+;;
+;; Finally, we use the bootstrap toolchain to build the OpenJDK with the
+;; Icedtea 1.x build framework. We then build the more recent JDKs Icedtea
+;; 2.x and Icedtea 3.x.
