[XeTeX] making a format file of ConTeXt using XeTeX

[Dalyoung]

Here are my steps following the suggestions by Adan and by Jonathan.

1. creat a folder texmf.local/web2c/xetex/context
2. move cont-en.fmt created by XeTeX to the above folder
3. keep original cont-en.fmt in texmf.local/web2c/
4. run the two test files;
	 texexec --pdf demo-tex.tex - produce fine output
       texexec --xtx mytest.tex - produce output with font 
error(cmr10,...)

Hence, I think that there is no need to add a line;
  TEXFORMATS.xetex = $TEXFORMATS/{xetex,}//

I'll apply these steps to the another mac in my school on monday and 
see what happens.
If it will work well, then I'll try to add some line in ConTeXt wiki. I 
have no experience in adding lines in wiki, but I'll try.

Thanks a lot.
