     When kpathsea is used to find files, \LUATEX\ uses the \type {ofm} file
     format to search for font metrics. In turn, this means that 
\LUATEX\ looks at
     the \type {OFMFONTS} configuration variable (like \OMEGA\ and 
\ALEPH) instead
     of \type {TFMFONTS} (like \TEX\ and \PDFTEX). Likewise for virtual 
fonts
     (\LUATEX\ uses the variable \type {OVFFONTS} instead of \type 
{VFFONTS}).
