 The Coyote Library evolved from work David Fanning was doing teaching
 IDL courses and answering IDL questions on the IDL newsgroup. It is
 meant to be a well-documented library that demonstrates how to write
 solid IDL/GDL programs that are easy to maintain and extend.
 .
 The main content of the library is the Coyote Graphics System (CGS),
 a collection of Coyote Library programs that turn the traditional
 GDL/IDL graphics commands (e.g., Plot, Contour, Surface, TV, etc.)
 into modern programs.
 .
 The most important features of Coyote Graphics System are:
 .
  * The commands work identically on the display, in PostScript, and
    in the Z-graphics buffer.
  * The commands can be displayed automatically in resizable graphics
    windows.
  * The commands automatically create high quality PostScript, PDF,
    and raster file output.
  * CGS graphics visualizations can be saved and restore later, or
    e-mailed to colleagues.
  * The commands work identically in an indexed or decomposed color
    environment.
  * The commands can use colors by name (e.g., "red", "dodger blue").
  * CGS commands are faster (often much faster) than the equivalent
    IDL function graphics commands.
  * Greek letters and other symbols can be directly embedded in Coyote
    Graphics text.
  * The commands fix the most annoying quirks (e.g., contour holes and
    levels) in traditional IDL commands.
