+=head NOTES
+
+This module uses Term::Cap to retrieve the formatting escape sequences for
+the current terminal, and falls back on the ECMA-48 (the same in this
+regard as ANSI X3.64 and ISO 6429, the escape codes also used by DEC VT100
+terminals) if the bold, underline, and reset codes aren't set in the
+termcap information.
