#   Description:    "ng4ex" provides the user with access to several
#                   C, Fortran, and NCL examples illustrating the use
#                   of the NCAR Graphics HLUs (High Level Utilities)
#                   and NCL.
# 
# The current "objects" that "ng4ex" demonstrates include the following:
# 
#     object name           abbrev. name
#     -----------           ------------
#     app                       ap
#     basic                     basic
#     contourplot               cn
#     labelbar                  lb
#     legend                    lg
#     primitives                pr
#     mapplot                   mp
#     ngmath                    nm
#     textitem                  tx
#     tickmark                  tm
#     title                     ti
#     streamlineplot            st
#     vectorplot                vc
#     xyplot                    xy
#
#     GSUN examples             gsun
#
#     NCL User Guide examples   nug   ( added in NCL V6.4.0 )
#
# How to add an example to this script:
#
#   First add it to appropriate variable below (c_xyplot, f_vector,
#   n_textitem, etc.).
#
#   If it is one of the "special" examples, then you'll also need to
#   add it to one or more of the following variables:
#
#    anno_list:  Annotation example
#    gui_list:   GUI example
#    cdf_list:   Reads or writes a netCDF file
#    x_list:     An example that always creates an X window (this
#                list was created so that if a user runs "ng4ex -W ncgm"
#                it won't try to generate examples that will always 
#                produce an X11 window).  GUI examples should be included
#                in this list.
