+# * Order-only dependencies: |
+#
+# Dependencies placed after a bar (|) should be built before
+# the current rule, but having one of them is out-of-date do not
+# trigger a rebuild of the current rule.
+# See http://www.gnu.org/software/make/manual/make.html#Prerequisite-Types
+#
+# * Annotation before commands: +/-/@
+#
+# a command starting by - is always successful (errors are ignored)
+# a command starting by + is runned even if option -n is given to make
+# a command starting by @ is not echoed before being runned
+#
+# * Custom functions
+#
+# Definition via "define foo" followed by commands (arg is $(1) etc)
+# Call via "$(call foo,arg1)"
+#
+# * Useful builtin functions
+#
+# $(subst ...), $(patsubst ...), $(shell ...), $(foreach ...)
+#
+# * Behavior of -include
+#
+# If the file given to -include doesn't exist, make tries to build it,
+# but doesn't care if this build fails. This can be quite surprising,
+# see in particular the -include in Makefile.stage*
