- copy ATARIST to localedata/charmaps/ATARIST
- cd iconvdata
- add ATARIST to the list of modules in Makefile
- add atarist to the list of gen-8bit-modules in Makefile
- copy atarist.c to this directory
- cd to topdir; run make
- copy iconvdata/ATARIST.so to /usr/lib64/gconv

- add some lines to /usr/lib64/gconv/gconv-modules:

#	from			to			module		cost
alias	ATARI//			ATARIST//
module	ATARIST//		INTERNAL		ATARIST		1
module	INTERNAL		ATARIST//		ATARIST		1

- run iconvconfig as root to rebuild /usr/lib64/gconv/gconv-modules.cache

The header file can be build with
  sh ./gen-8bit.sh ../localedata/charmaps/ATARIST > atarist.h
(but this should already be done by make)
