 # 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) yasm_config -- General build configuration including setting a
 #              source_prereqs listing the checked in version of files
 #              generated by manually running configure. These manually
 #              generated files are used by all binaries.
 #   3) yasm_utils -- Object files with memory management and hashing utilities
 #              shared between yasm and the genperf subprogram.
 #   4) genmacro, genmodule, etc. -- One executable target for each subprogram.
 #   5) generate_license, generate_module, etc. -- Actions that invoke programs
 #              built in #4 to generate .c files.
 #   6) compile_gperf, compile_re2c, etc. -- Actions that invoke programs that
 #              turn intermediate files into .c files.
