;   Description: Shows how to draw high-resolution coastlines using the
;   RANGS (Regionally Accessible Nested Global Shorelines), developed
;   by Rainer Feistel from Wessel and Smith's GSHHS (Global
;   Self-consistent Hierarchical High-resolution Shoreline) database.
;   To access the RANGS/GSHHS database, you must first download it from
;   Rainer Feistel's web site at
;   http://www.io-warnemuende.de/homepages/rfeistel/index.html.  Right
;   before the section entitled "Some WWW Links", you should see a
;   little table with ten *.zip files to download:
;
;     rangs(0).zip gshhs(0).zip
;     rangs(1).zip         gshhs(1).zip
;     rangs(2).zip         gshhs(2).zip
;     rangs(3).zip         gshhs(3).zip
;     rangs(4).zip         gshhs(4).zip
;
;   You must download all ten of these files, unzip them, and either
;   put them in the default directory
;   "$NCARG_ROOT/lib/ncarg/database/rangs", or put them somewhere else
;   and set the environment variable NCARG_RANGS to this directory. The
;   files take up about 140 megabytes, unzipped. Once you have the
;   files in the appropriate location, then set the mpDataBaseVersion
;   resource to "RANGS_GSHHS" to create maps using this database. You
;   should not use this database to plot maximal area plots, because 1)
;   you will get horizontal lines through your plot, and 2) it takes a
;   long time.
