2 This file should be located at the top of the OpenJDK Mercurial repository 2 This file should be located at the top of the OpenJDK Mercurial root
3 forest. This top or enclosing repository will include a "make" directory, 3 repository. This root repository will include a "make" directory,
4 and a Makefile at the very top of the repository. 4 and a Makefile for building the entire OpenJDK.
5 It should also include the 6 repositories: "jdk", "hotspot", "langtools", 5 A full OpenJDK repository set (forest) should also include the following
6 "corba", "jaxws" and "jaxp". 6 6 nested repositories:
7 "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp".
8 There are also several source downloads for the jax* repositories that
9 will be needed.

11 This one root repository can be obtained with something like:
12 hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7
13 To make sure you have all the nested repositories, you can run:
14 cd openjdk7 && sh ./get_source.sh
15 (This is identical to using the Mercurial Forest Extension command
16 'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7').
17 People unfamiliar with Mercurial should read the first few chapters of
18 the Mercurial book: http://hgbook.red-bean.com/read/
