[Chicken-users] Chicken module and application project source structure
chicken-users: For a noob first project, I would like to write a command-line utility in Chicken Scheme: Usage: update [options] [src] dst Copy file src to file dst if contents are different. Read STDIN if src is '-' or if src is omitted. Options: --create Create dst if it does not exist (default) --nocreateExit with error if dst does not exist I would like to put the functionality into a library source file and put the command-line interface into a program source file that includes or uses the library. Is there an convention for Chicken project source directory and file structure? What about toolchain conventions? (E.g. Makefile?) Is there anything analogous to Perl's h2xs, module-starter, ExtUtils::MakeMaker, Module::Build, etc?
