# buildTypeLabel (interim, milestones, releases)

# sitexmlOut (site.xml)  && coordsitexmlOut (site-ganymede.xml)
# coordsiteSuffix (ganymede)
# header (/path/to/header.${buildTypeLabel}) -- actual file will be header.interim.site.xml or header.releases.site-ganymede.xml
# targetDir (/path/to/output/the/site.xml file)
# sourceDirs (one or more dirs whose contents to merge
