+Setting Flags
+=============
+
+Maje recognizes some flags in source code that can be automatically added into
+the resulting Makefile. The following, followed by an equal sign, are copied
+up to the first white space character as indicated:
+
+    MAJE_CFLAG		Added to the CFLAGS macro
+    MAJE_LDFLAG		Added to the LDFLAGS macro
+    MAJE_LDLIB		Added to the LDLIBS macro
+
+Maje will find these strings anywhere in your source file, so long as they
+are followed by an equal sign, one or more characters, and a whitespace
+character. Comments are a good place for them.
