DESA.EXE is a beta-release of a GEMA disassembler. A complete interactive
real and protected-mode debugger is in progress.

ASM2GEMA.EXE is a TASM to GEMA translator. The current release is v1.22 and
is available separately, surely on the site you found GEMA on, and even more
surely on GEMA's support sites.

These two utilities are under development by Altomcat from Sector One
( alt_sct1@the_one.epita.fr ) . They were included in this package just for
fun, but their final release will soon be available.
