+
+# The yasm build process creates a slew of small C subprograms that
+# dynamically generate files at various point in the build process.  This makes
+# the build integration moderately complex.
+#
+# There are three classes of dynamically generated files:
+#   1) C source files that should be included in the build (eg., lc3bid.c)
+#   2) C source files that are #included by static C sources (eg., license.c)
+#   3) Intermediate files that are used as input by other subprograms to
+#      further generate files in category #1 or #2.  (eg., version.mac)
+#
+# This structure is represented with the following targets:
+#   1) yasm -- Sources, flags for the main yasm executable. Also has most of
+#              of the actions and rules that invoke the subprograms.
+#   2) config_sources -- Checked in version of files generated by manually
+#                        running configure that are used by all binaries.
+#   3) generate_files -- Actions and rules for files of type #3.
+#   4) genperf_libs -- Object files shared between yasm and the genperf
+#                      subprogram.
+#   5) genmacro, genmodule, etc. -- One executable target for each subprogram.
+#
+# You will notice that a lot of the action targets seem very similar --
+# especially for genmacro invocations. This makes it seem like they should
+# be a rule. The problem is that the correct invocation cannot be inferred
+# purely from the file name, or extension.  Nor is it obvious whether the
+# output should be processed as a source or not.  Thus, we are left with a
+# large amount of repetitive code.
