  * -f or --fixed If specified, all characters will have the same width. By
  default fonts are assumed to be variable pitch.
- * -x or --xmap Specifies horizontal mapping (default is vertical).
+ * -x or --xmap Specifies horizontal mapping (this is the default).
+ * -y or --ymap Vertical mapping for specialist display hardware. Not compatible

  * -r or --reverse Specifies bit reversal in each font byte.
