"""Module for handling Qt Phrase Book (.qph) files.

.qph Qt Phrase Book Files are human-readable XML files containing standard
phrases and their translations. These files are created and updated by Qt
Linguist and may be used by any number of projects and applications.
A DTD to define the format does not seem to exist, but the following U{code
