+#                LUFA CPPCheck Buildsystem Makefile Module.
+# -----------------------------------------------------------------------------
+# DESCRIPTION:
+#   Provides a set of targets to scan a project with the free "cppcheck" static
+#   analysis tool, to check for code errors at runtime (see http://cppcheck.sourceforge.net).
+# -----------------------------------------------------------------------------
+# TARGETS:
+#
+#    cppcheck                  - Scan the project with CPPCheck
+#    cppcheck-config           - Use CPPCheck to look for missing include files
+#
+# MANDATORY PARAMETERS:
+#
+#    (None)
+#
+# OPTIONAL PARAMETERS:
+#
+#    CPPCHECK_PATH             - Path of the files to statically analyze
+#    CPPCHECK_INCLUDES         - Extra include paths to search for missing
+#                                header files
+#    CPPCHECK_EXCLUDES         - Source file paths to exclude checking (can be
+#                                a path fragment if desired)
+#    CPPCHECK_MSG_TEMPLATE     - Template for cppcheck error and warning output
+#    CPPCHECK_ENABLE           - General cppcheck category checks to enable
+#    CPPCHECK_SUPPRESS         - Specific cppcheck warnings to disable by ID
+#    CPPCHECK_FAIL_ON_WARNING  - Set to Y to fail the build on cppcheck
+#                                warnings, N to continue even if warnings occur
+#    CPPCHECK_QUIET            - Enable cppcheck verbose or quiet output mode
+#
