 # 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)

 # 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 repetative code.
