types and functions used to represent SGR aspects; profiling libraries

 The ANSI standards refer to the visual style of
 displaying characters as their 'graphic rendition'. The
 ANSI codes to establish the graphic rendition for
 subsequent text are referred to as SELECT GRAPHIC RENDITION
 (SGR). This package exposes modules that export types and
 functions used to represent SGR aspects.
 .
 This package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
