     Failure to follow this procedure might result in hard-to-debug build
     problems.
 
-### Using get\_source.sh
-
-The simplest way to get the entire forest is probably to clone the top-level
-repository and then run the `get_source.sh` script, like this:
-
-```
-hg clone http://hg.openjdk.java.net/jdk9/jdk9
-cd jdk9
-bash get_source.sh
-```
-
-The first time this is run, it will clone all the sub-repositories. Any
-subsequent execution of the script will update all sub-repositories to the
-latest revision.
-
-### Using hgforest.sh
-
-The `hgforest.sh` script is more expressive than `get_source.sh`. It takes any
-number of arguments, and runs `hg` with those arguments on each sub-repository
-in the forest. The `get_source.sh` script is basically a simple wrapper that
-runs either `hgforest.sh clone` or `hgforest.sh pull -u`.
-
-  * Cloning the forest:
-    ```
-    hg clone http://hg.openjdk.java.net/jdk9/jdk9
-    cd jdk9
-    bash common/bin/hgforest.sh clone
-    ```
-
-  * Pulling and updating the forest:
-    ```
-    bash common/bin/hgforest.sh pull -u
-    ```
-
-  * Merging over the entire forest:
-    ```
-    bash common/bin/hgforest.sh merge
-    ```
-
-### Using the Trees Extension
-
-The trees extension is a Mercurial add-on that helps you deal with the forest.
-More information is available on the [Code Tools trees page](
-http://openjdk.java.net/projects/code-tools/trees).
-
-#### Installing the Extension
-
-Install the extension by cloning `http://hg.openjdk.java.net/code-tools/trees`
-and updating your `.hgrc` file. Here's one way to do this:
-
-```
-cd ~
-mkdir hg-ext
-cd hg-ext
-hg clone http://hg.openjdk.java.net/code-tools/trees
-cat << EOT >> ~/.hgrc
-[extensions]
-trees=~/hg-ext/trees/trees.py
-EOT
-```
-
-#### Initializing the Tree
-
-The trees extension needs to know the structure of the forest. If you have
-already cloned the entire forest using another method, you can initialize the
-forest like this:
-
-```
-hg tconf --set --walk --depth
-```
-
-Or you can clone the entire forest at once, if you substitute `clone` with
-`tclone` when cloning the top-level repository, e.g. like this:
-
-```
-hg tclone http://hg.openjdk.java.net/jdk9/jdk9
-```
-
-In this case, the forest will be properly initialized from the start.
-
-#### Other Operations
-
-The trees extensions supplement many common operations with a trees version by
-prefixing a `t` to the normal Mercurial command, e.g. `tcommit`, `tstatus` or
-`tmerge`. For instance, to update the entire forest:
-
-```
-hg tpull -u
-```

 <p>To be able to run JTReg tests, <code>configure</code> needs to know where to find the JTReg test framework. If it is not picked up automatically by configure, use the <code>--with-jtreg=&lt;path to jtreg home&gt;</code> option to point to the JTReg framework. Note that this option should point to the JTReg home, i.e. the top directory, containing <code>lib/jtreg.jar</code> etc. (An alternative is to set the <code>JT_HOME</code> environment variable to point to the JTReg home before running <code>configure</code>.)</p>
