Updating build_doc.xml

Before using, create the build/artifacts/doc/build_out directory if it doesn't already exist.

To build all docs and the master TOC with the ant script:

ant -buildfile build/build_doc.xml

To build the master TOC alone (assuming you’ve already built the docs separately):

ant -buildfile build/build_doc.xml buildMasterTOC

In Xcode, you can also use project-specific targets to build docs for a specific project. However, you must use the ant script to build the master TOC.

All output goes to build/artifacts/doc/build_out.
