+     "Tamzen is a fork of the @code{Tamsyn} font.  It is programatically forked
+from @code{Tamsyn} version 1.11, backporting glyphs from older versions while
+deleting deliberately empty glyphs (which are marked as unimplemented) to
+allow secondary/fallback fonts to provide real glyphs at those codepoints.
+
+The @code{TamzenForPowerline} fonts provide additional @code{Powerline} symbols,
+which are programatically injected with @code{bitmap-font-patcher} and
+later hand-tweaked with the gbdfed(1) editor:
+
+@enumerate
+@item all icons are expanded to occupy the maximum available space
+@item the branch of the fork icon ( U+E0A0) was made larger than the trunk
+@item for the newline icon ( U+E0A1), the @emph{N} was made larger at the bottom
+@item the keyhole in the padlock icon ( U+E0A2) was replaced with @emph{//} lines.
+@end enumerate\n")
