フォント利用英文説明引用文
These are release versions of the GNU FreeFont fonts.
You probably want to get just one of them, the one with the most recent date,
that matches your needs.
As of the 2012 release,
The "ttf" files are TrueType, (strongly) preferred for Windows.
(In releases prior to 2012, OpenType was preferred for Windows, and TrueType
for other systems. The essential difference is that now the internal format
of the letters in the OpenType files is cubic spline (PostScript) and of the
TrueType is quadratic spline (TrueType).)
