|  | # 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 | 
|  | #              inputs 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. |
