  This file should be located at the top of the OpenJDK Mercurial root
  repository. This root repository will include a "make" directory,
  and a Makefile for building the entire OpenJDK.
  A full OpenJDK repository set (forest) should also include the following
  6 nested repositories:
    "jdk", "hotspot", "langtools", "corba", "jaxws"  and "jaxp".
  There are also several source downloads for the jax* repositories that
  will be needed.

  This one root repository can be obtained with something like:
    hg clone openjdk7
  To make sure you have all the nested repositories, you can run:
    cd openjdk7 && sh ./
  (This is identical to using the Mercurial Forest Extension command 
   'hg fclone openjdk7').
  People unfamiliar with Mercurial should read the first few chapters of
  the Mercurial book:

  See for more information about the OpenJDK.

Simple Build Instructions:
  0. Get the necessary system software/packages installed on your system, see

  1. If you don't have a jdk6 installed, download and install a JDK 6 from
     Set the environment variable ALT_BOOTDIR to the location of JDK 6.

  2. Check the sanity of doing a build with your current system:
       gnumake sanity
     See README-builds.html if you run into problems.
  3. Do a complete build of the OpenJDK:
       gnumake all
     The resulting JDK image should be found in build/*/j2sdk-image

where gnumake is GNU make 3.81 or newer, /usr/bin/make on Linux and
/usr/sfw/bin/gmake or /opt/sfw/bin/gmake on Solaris.
