IZREADME.SMS release notes from Jonathan Hudson (author of port)
Makefile makefile for xtc68 cross-compiler on Linux (native QDOS exes)
callstub.c user interface stub for SMS/QDOS specific SFX archives
config.S assembler routine for ...?
crc68.s 68000 version of CRC code
izqdos.h SMS/QDOS-specific header file
makesfx.c source for MakeSFX utility (simple concatenation does not work)
qdos.c SMS/QDOS-specific functions
Notes:
"Makefile" is for the xtc68 cross compiler on Linux, but conversion to a
native c68 makefile should be trivial. To build a Linux (or other Unix)
UnZip that understands QDOS extra fields, add "-DQLZIP" to the LOCAL_UNZIP
environment variable and compile with the normal Unix makefile (for example,
linux_asm target). The "QLZIP" flag enables the Qdos "cross-UnZip" support
in unix/unix.c.
