[XeTeX] Windows tools in XeTeX - what do they do?

[Mojca Miklavec]

Hello,

There are some new executables in w32tex's XeTeX.

sfconv.exe
teckit_compile.exe
txtconv.exe

What are they used for (I have no windows computer here to try)?

So far, I only kept extracting the following files:

fc-cache.exe
fc-list.exe
icudt38.dll
kpathsea35671.dll
msvcp71.dll
msvcr71.dll
xdvipdfmx.exe
xetex.dll
xetex.exe

and wonder whether the other files are needed too or not.

Thanks,
   Mojca
