 Comment:
 
-In ConTeXt MkIV we have two core scripts: luatools.lua and
-mtxrun.lua where the second one is used to launch other scripts.
+In ConTeXt MkIV we have two core scripts: luatools.lua and mtxrun.lua where the
+second one is used to launch other scripts. The mtxrun.exe program calls luatex.exe.
+
 Normally a user will use a call like:
 
-mtxrun --script font --reload
+    mtxrun    --script font --reload
+
+Here mtxrun is a lua script. In order to avoid the usage of a cmd file on windows this
+runner will start texlua directly. In TeXlive a runner is added for each cmd file but
+we don't want that overhead (and extra files). By using an exe we can call these
+scripts in batch files without the need for using call.
+
+The mtxrun.exe file can be copied to a mtxrunjit.exe file in which case luajittex.exe
+is called.
