When files like -vfn: or -TEXPK: are specified, the directory where dviout is installed can be specified as the standard.
If "^x" is added at the beginning of the path name, it is replaced by the dviout installation directory. For example, if dviout.exe was installed in c:\dviout, the setting
-gen:^x\utility\template
is identical to the
-gen:c:\dviout\utility\template
setting.
