+.RI GNU \~@g@troff (@MAN1EXT@),
+and writes the combined result to the standard output.
+.
+The information added is derived from the font's existing parameters and
+assumptions about traditional
+.I troff
+names for characters.
+.
+Among the font metrics added are the heights and depths of characters
+(how far each extends vertically above and below the baseline).
+.
+The
+.I resolution
+and
+.I unit-width
+arguments should be the same as the corresponding parameters in the
+.I DESC
+file.
+.
+.I font
+is the name of the file describing the font;
