+# We have two different modes of operation: 1) put stuff specific to Port X
+# in subdirectory X and have that subdirectory's make file make it all, and
+# 2) use conditional statements in the present make file to include what's
+# necessary for a specific port in our own output. (1) came first, but (2)
+# is superior for many things, like when the same thing needs to be done for
+# multiple ports and you don't want to duplicate files in multiple
+# subdirectories. Much of the stuff done via Method 1 today should probably
+# be converted to Method 2.
