# action. Otherwise Boost Jam might, under some circumstances, run only some of
# our actions. To achieve this we register a series of actions for all the
# targets (since they all have the same target list - either all or none of them
# get run independent of which target actually needs to get built), each
# building only a single target. Since all our actions use the same targets, we
# can not use 'on-target' parameters to pass data to a specific action so we
# pass them using the second 'sources' parameter which our actions then know how
# to interpret correctly. This works well since Boost Jam does not automatically
# add dependency relations between specified action targets & sources and so the
# second argument, even though most often used to pass in a list of sources, can
# actually be used for passing in any type of information.
