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.
