#    Description:
#      This file is the automake footer for all code-coverage related
#      targets and rules.
#
#      This represents the minimum integration with GNU autotools
#      (automake in particular) such that 'make coverage' may be invoked
#      at the top of the tree and all the prerequisites occur such
#      that it executes successfully with no intervening make target
#      invocations. The 'check-am' and '$(BUILT_SOURCES)' are the key
#      automake-specific dependencies to ensure that happens.
#
#      This defines the following make targets:
#
#        coverage:
#          Execute local and recursive coverage targets across the
#          project sub-tree at the current invocation point.
#
#          This target is intended to be user-visibile and -invoked.
#
#        coverage-local:
#          Execute local coverage targets at the current invocation point.
#
#          This target is intended to be user-visibile and -invoked.
#
#        coverage-recursive:
#          Recursively execute the 'coverage' target across the
#          project sub-tree at the current invocation point.
#
#          This target is NOT intended to be user-visibile and -invoked.
#
#        check-local:
#          Alias for the 'check-am' target. Execute local check
#          targets at the current invocation point. Local coverage targets
#          may depend on this to ensure local tests are made before
#          coverage targets are made.
#
#          This target is intended to be user-visibile and -invoked.
