'''
Usage:
test.py [path]
Validates all xml files against the DocBook 5 RELAX NG schema, and
attempts to build all books.
Options:
path Root directory, defaults to <repo root>/doc
Ignores pom.xml files and subdirectories named "target".
Requires:
- Python 2.7 or greater (for argparse)
- lxml Python library
- Maven
