+#              rule
+# DSTS (Dependency Suffix     Target Suffix)
+# 'TS' is the suffix of the target file, 'DS' is the suffix of the dependency
+#  file, and 'rule'  is the rule for building a target
+# '$*' is a built-in macro that gets the basename of the current target
+# Remember that there must be a < tab > before the command line ('rule')
