+# There exist several targets which are by default empty and which can be
+# used for execution of your targets. These targets are usually executed
+# before and after some main targets. They are:
+#
+# .build-pre: called before 'build' target
+# .build-post: called after 'build' target
+# .clean-pre: called before 'clean' target
+# .clean-post: called after 'clean' target

+# .all-pre: called before 'all' target
+# .all-post: called after 'all' target
+# .help-pre: called before 'help' target
+# .help-post: called after 'help' target
+#
+# Targets beginning with '.' are not intended to be called on their own.
+#
+# Main targets can be executed directly, and they are:
+#
+# build build a specific configuration
+# clean remove built files from a configuration
+# clobber remove all built files
+# all build all configurations
+# help print help mesage
+#
+# Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
