Certainly emTeX is obsolete and dead. Jun Sawataishi prepared another
distribution based upon teTeX and his own tool for porting programs
from Linux. It heavily uses bash scripts and perl scripts, both bash
and perl are ported to OS/2. Jun Sawataishi works on it irregularly
when he thinks that some new version is important for him. I suggested
to him to contact TL developers but he never did, everything is
available from his web site only. Although all his tools are freely
available and their use for compiling TeX is described, I have no time
to do it myself. He did not compile XeTeX and I am afraid that it will
be next to impossible due to lack of support of Unicode in OS/2. One
day Jun Sawataishi may decide that luatex is important but nobody
knows whether it happens.
