The cc65 cross-compiler suite
=============================

cc65 is a complete cross-development package for 65(C)02 systems,
including a powerful macro assembler, a C compiler, linker, archiver,
simulator and several other tools.  cc65 has C and runtime library
support for many of the old 6502 machines.  For details look at
the [cc65 web site](https://cc65.github.io):

## People

cc65 is originally based on the "Small C" compiler by Ron Cain and
enhanced by James E. Hendrix.

### Project founders

* John R. Dunning: [original implementation](https://public.websites.umich.edu/~archive/atari/8bit/Languages/Cc65/)
  of the C compiler and runtime library, Atari hosted.
* Ullrich von Bassewitz:
  * moved Dunning's code to modern systems,
  * rewrote most parts of the compiler,
  * rewrote all of the runtime library.
