Hi,
 
many context users are also luatex user, and the context standalone also contains luatex binary (windows). I input the 'luatex' in the cmd, but it can't work. The message is as follows:
 
d:\>luatex
luatex
This is LuaTeX, Version beta-0.77.0-2013041621 (rev 4633)
 \write18 enabled.
**\relax
I can't find the format file `luatex.fmt'!
kpathsea: Running mktexfmt luatex.fmt
The command name is D:\context\tex\texmf-mswin\bin\mktexfmt
 
Since there is not mktexfmt in the context standalone, is that mean I can't use plain luatex in the context standalone?
