+cl65 is a frontend for cc65, ca65, co65 and ld65. While you may not use the
+full power of the tools when calling them through cl65, most features are
available, and the use of cl65 is much simpler.
Basic Usage
-The cl65 compile and link utility may be used to compile, assemble and
-link files. While the separate tools do just one step, cl65 knows how to
-build object files from C files (by calling the compiler, then the
-assembler) and other things.
