The purpose of this module is to parse through the XML documents
in the project and generate a list of
all the binary documents which are actually used (since there are
many hanging around in the repo which are never referenced).
This list will be used by the ant static build task to
copy over only those documents we actually need into the output
images folder. The file will be a flat text file listing
the filenames of these files.
