cc65 is a complete cross development package for 65(C)02 systems, including
a powerful macro assembler, a C compiler, linker, librarian and several
other tools.

cc65 has C and runtime library support for many of the old 6502 machines,
including

- the following Commodore machines:
  - VIC20
  - C16/C116 and Plus/4
  - C64
  - C128
  - CBM 510 (aka P500)
  - the 600/700 family
  - newer PET machines (not 2001).
- the Apple ]\[+ and successors.
- the Atari 8-bit machines.
- the Atari 2600 console.
- the Atari 5200 console.
- GEOS for the C64, C128 and Apple //e.
- the Bit Corporation Gamate console.
- the NEC PC-Engine (aka TurboGrafx-16) console.
- the Nintendo Entertainment System (NES) console.
- the Watara Supervision console.
- the VTech Creativision console.
- the Oric Atmos.
- the Oric Telestrat.
- the Lynx console.
- the Ohio Scientific Challenger 1P.
- the Commander X16.

The libraries are fairly portable, so creating a version for other 6502s
shouldn't be too much work.
