+##module
+# - The builtin graphviz support of CMake.
+# CMake can generate graphviz files, showing the dependencies between
+# the targets in a project and also external libraries which are linked
+# against.
+# When CMake is run with the --graphiz=foo option, it will produce
+#    * a foo.dot file showing all dependencies in the project
+#    * a foo.dot.<target> file for each target, file showing on which other targets the respective target depends
+#    * a foo.dot.<target>.dependers file, showing which other targets depend on the respective target
+#
+# This can result in huge graphs. Using the file CMakeGraphVizOptions.cmake
+# the look and content of the generated graphs can be influenced.
+# This file is searched first in ${CMAKE_BINARY_DIR} and then in
+# ${CMAKE_SOURCE_DIR}. If found, it is read and the variables set in it
+# are used to adjust options for the generated graphviz files.
