      Kochi Gothic and Kochi Mincho were developed as free replacements for the
      MS Gothic and MS Mincho fonts from Microsoft. This version of the fonts
      includes some non-free glyphs from the naga10 font, which stipulate that
      this font may not be sold commercially. See kochi-substitute for the free
      Debian version.
