; NAME: crib_tplot_export_print
; 
; PURPOSE:  Crib to demonstrate tplot export commands
;           You can run this crib by typing:
;           IDL>.compile crib_tplot_export
;           IDL>.go
;           
;           When you reach a stop, press
;           IDL>.c
;           to continue
;           
;           Or you can copy and paste commands directly onto the command line
;
; SEE ALSO: crib_tplot.pro  (basic tplot commands)
;           crib_tplot_layout.pro  (how to arrange plots within a window, and data within a plot)
;           crib_tplot_range.pro   (how to control the range and scaling of plots)
;           crib_tplot_annotation.pro  (how to control labels, titles, and colors of plots)
;
; NOTES:
;   If you see any useful commands missing from these cribs, please let us know.
;   these cribs can help double as documentation for tplot.
