+@code{nil} means to use the internal ELisp-based @code{uncompface}
+program.  @code{t} means to use the external decoder.  The default value
+is normally @code{undecided} which means to determine it by checking
+whether the host machine is slow, being controlled by
+@code{uncompface-use-external-threshold} (which see).

+@item uncompface-use-external-threshold

+If the internal decoder is invalidated or if you are using XEmacs,
+decoding an @code{X-Face} header either requires an Emacs that has
 @samp{compface} support (which most XEmacs versions has), or that you
 have @samp{compface} installed on your system.  If either is true,
 Gnus will default to displaying @code{X-Face} headers.
