# This is a very quick and dirty attempt to figure some metrics for our tests
# It monitors all qml files with inotifywatch and generates a cobertura
# compatible coverage.xml file containing the statistics. This is far from
# perfect but its a start and indeed gives somewhat meaningful numbers
#
# If this proves to be useful, it probably could/should be rewritten
# in a more robust and flexible way, preferably in a language where
# floating point operations and xml writing is natively supported.
