+#  The depend target has to cope with a set of files that may have
+#  different ways of computing their dependencies, i.e., a Haskell

+#
+# Note that we don't compute dependencies automatically, i.e., have the
+# .depend file be a target that is dependent on the Haskell+C sources,
+# and then have the `depend' target depend on `.depend'. The reason for
+# this is that when GNU make is processing the `include .depend' statement
+# it records .depend as being a Makefile. Before doing any other processing,
+# `make' will try to check to see if the Makefiles are up-to-date. And,
+# surprisingly enough, .depend has a rule for it, so if any of the source
+# files change, it will be invoked, *regardless* of what target you're making.
+#
+# So, for now, the dependencies has to be re-computed manually via `make depend'
+# whenever a module changes its set of imports. Doing what was outlined above
+# is only a small optimisation anyway, it would avoid the recomputation of
+# dependencies if the .depend file was newer than any of the source modules.
