Merged Dart Editor build notes into README.

-Building the Dart Editor RCP distro
-
-Assuming Dart sources are checked out, there are four steps to building
-Dart Editor. This process is only required because the RCP export wizard
-cannot handle linked resources. The steps are:
-
-1. Copy all the sources into a working directory.
-2. Build an Eclipse workspace from the working directory.
-3. Create the distro using Eclipse's Product export wizard.
-4. Rename the export diretory and compress it into an archive file.
-
-Step 1 is automated by the rcpinit.sh bash shell script, in the same
-directory as this README. It also uses emptyDartWorkspace.zip (in the
-same directory) to initialize  step 2.
-
-Step 2 is completed manually, as is step 3. Step 4 is optional.
-
-It is recommended that all files in this build directory be copied into the
-parent directory of TRUNK (as defined in rcpinit.sh).
-
-To begin, make sure the Dart plugin and feature sources are checked out from
-SVN. Edit rcpinit.sh to define the location of the TRUNK directory that was
-checked out. Also checkout the usage profile plugin and feature from perforce.
-Define that directory in rcpinit.sh as GDT_PROF. You only the the usage
-profiler, not all of GPE.
-
-From a terminal emulator, cd to the directory containing the customized
-rcpinit.sh and execute it. That completes step 1, and initializes step 2.
-Note that a new directory called workDart is created. It contains a copy
-of all the sources needed to build the distro.
-
-Start up Eclipse. Switch workspace to the workDart directory created by
-rcpinit.sh. Import the existing projects into Eclipse, but do not copy them.
-
-Open the dart_feature.product definition (in com.google.dart.tools.deploy) in
-the Product Editor (double-click it). Find the "Exporting" section in the lower
-right, and click the "Eclipse Product export wizard" link to start the wizard.
-Select an output directory. It should be empty to start; re-using a directory
-does not clear out old stuff and can cause problems. You can uncheck the
-"Generate metadata repository" option. Allow the wizard to finish.
-
-In the selected output directory, rename the "eclipse" directory to "darttools"
-then compress it for distribution. Finally, test the result. Reversing those
-steps seems logical, but testing creates a lot of files and directories that
-should not be distributed. To test the distro, import the Total app, build it,
-and run it. Try a few editor functions like code completion and hyperlinking.
-
-Note: To get the usage profiler without getting all of GPE you can use a two
-stage checkout. Log into your Ubiquity instance, create a new directory, cd
-into it and do:
-
-git5 start trunk google3/third_party/java/google_plugin_eclipse/opensource/trunk/plugins/com.google.gdt.eclipse.usageprofiler
-git5 track google3/third_party/java/google_plugin_eclipse/opensource/trunk/features/com.google.gdt.eclipse.usageprofiler.feature
-
-Then use 'git clone' to make that directory available to your build machine.
-In rcpinit.sh, change GDT_PROF to point to the cloned directory. Of course,
-you only need to clone it if you are building on a Mac.
-
-Note: These instructions only create an executable that runs on the same
-platform as the build box. Cross-platform building requires some additional
-work, including downloading the delta pack from eclipse.org.
